PERTEMUAN 2: HITUNG CEPAT - BIMBEL SKD CPNS 2026 BATCH 3

Is the voice less harsh or safe? Of course it's safe. If it's not harsh, it means the network is there, which has to be corrected. Because the network here is safe, friends. I also heard directly from YouTube here, it's okay, there's no problem.

Okay, so today we will enter the first meeting for the main material. So yesterday we have learned one meeting, but yesterday was the basic Tiu, so we haven't entered the main material.

Basic TU is the core of the main TU which is numerical, friends. The main one with the calculation. So it will be very difficult to understand the fast calculation and its friends if you don't follow the basic TU yesterday. Now, maybe there are some who just joined today.

Because it's always like that from the previous batch meetings, there must be someone who is late on the first day. My advice for friends who have just joined and haven't had time to watch the basic Tio recording,

You may find a struggle in understanding the material tonight But it's okay, just follow it first Because this class will have a recc. Later, friends, after seeing the basic TU recc. You can see the recc. for tonight's class Insya Allah the connection will be different So it's okay to follow the class tonight Just follow the course, later you can see the basic TU again, okay?

Stop it, Zip. Wait, wait, wait. Wait, okay? Okay, where's my pen?

For tonight, the issue that we will discuss tonight has been shared on the website and on Telegram. So you can work in the afternoon or in the afternoon. So you can try to work with the CAT system, it can also be printed.

can be sorted and prepared tonight to discuss together so don't be surprised later when I give polling to friends then why is it so fast to choose the answer? Yes, because they have worked before so maybe some of you don't know the technique

So after that, friends, you can work first, you can study first, and tonight we discuss together how to be the most effective way to work on that issue. Okay? Now before we start, don't forget to pray, according to each of us, hopefully what we learn tonight will be one of the ammunition for you to complete the next test. Amen. Pray starting now.

Okay friends, please share the screen. For PR and quiz, the PR is on the website, the quiz is on Telegram, the questions today are also on the website, on your respective accounts. Okay friends on YouTube, Bismillah, let's start now. I will not activate the comments first, I will open it again later.

Okay, friends, so we are already in the fast calculation, so this is one of the issues that has never been absent from the past until now, the fast calculation is always in the CPNS test from the past to the present, from the CPNS of the past to the CPNS of the present, so this is not there

There is no excuse not to study this because the number of questions is very large in Tiu, friends. It can be up to 4-5 questions. It's quite 25 points if you are all right here. Now, there are some lists.

special pieces, yes, actually what makes it special is because it often comes out like that, friends, so we will share the list later, the file, friends, can download the PPT file later, so you can print it, you can save it in

Your device can also be like that. So, like, one in two is the same as the decimal with 0.5 if the percentage is 50%. What often comes out is also 1 in 4. 1 in 4 is 0.25, then the percentage is 25%.

4/5, 4/5 is 0.8, the percentage is 80%. 1/8 is 0.125 and 12.5%, it often comes out. So just look at it, don't memorize it, the important thing is to work on the issue often, you must memorize it yourself.

Now, we're going to go to question number one. Before I discuss, I will give a polling to you guys. What was your answer? Please choose the answer you answered earlier. I'll give you 30 seconds so it won't be too long. Friends on YouTube, you can comment on the comments column what your answer is for this number one. Can't you go to Zoom? Yes, you can. If you want to go to Zoom, please. If you want to go to YouTube, please. Everyone can.

Okay, so only 63% choose section B. Friends on YouTube, there is section B, there is section E. Okay, let's see, friends. Question number 1, pay attention to everything carefully, don't do anything else first, look at the flow carefully.

The result of 2 divided by 2 multiplied by 6 divided by 5 divided by 3 divided by -1 divided by 2 Okay, if you are working on the CPNS test, especially TU, friends, don't ever forget to list the choices, okay? Why? Because by looking at the choices, you guys become a guide, friends, what should I do? What should I change?

so that the way of working is not too much. So here the choice is the round number and the number of mixed fractions. Well, the problem here is all fractions. So we change it to ordinary fractions, friends. As I said yesterday, if the operation is a multiplication,

and division, then there is a mixture of fractions, it is mandatory to change it into a normal fraction. So we change it first into a normal fraction, the way yesterday, 2 times 2 is 4, plus 1 is equal to 5. It means the denominator is 5 times, follow this, 5 times 2.

Okay, divided by 6 divided by 5, we don't need to change it, we just write it. Then divided by 3 divided by 5. If the division is divided, we change it to times, then 3 divided by 5, we return it to 5 divided by 3. Okay, can you guys? Now, subtracted.

1 divided by 2, this 1 divided by 2 can be changed to a normal division, so 2 multiplied by 1, 2 plus 1 is equal to 3 divided by 2. Okay, so the way to change it is multiplied and then added.

Now there are times and decreases, of course we have to work on the times first. If we use the times, we can use the system of sorting, which I explained yesterday. The best we sort here, yes, it can be 5 by 5, each divided by 5.

5 divided by 5 is 1, 5 divided by 5 is 1. Then 6 with 2 is okay, 6 with 3 is also okay. So 6, for example, you choose 6 with 3 first is also okay, no problem. Or 6 with 2 first will also be the same result. Now 6 with 2 each divided by 2. 2 divided by 2 is 1, 6 divided by 2 is 5.

Now, 3 with 3, you can divide each by 3. 3 divided by 3 is 1. 3 divided by 3 is 1. Is there any more that can be subtracted? There is none, friends. So, the result, the one above, we multiply 1 by 1 by 5. So, 5 times 3.

5 times 1 is equal to 5, so 5 times 1 is equal to 5, so we just write 5. 5 minus 3 times 2. Now, I want to teach you another skill, how to change

How to reduce the number of circles with the number of fractions. This is the first way, friends. So there are two ways. The first way is to reduce 5 number of circles with number of fractions. We change the number of 5 to be a fraction. The way is

This is multiplied, 2 times 5 is 10. Then, follow this, so 10 divided by 2. 5, we change it to 10 divided by 2. 10 divided by 2 or 10 divided by 2 is 5, right? Reduced 3 divided by 2.

Okay, so 5 we change to 10/2, how do I repeat it? 2 times 5 is 10, so the name 10 follows here. Now 10 minus 3 is equal to 7/2.

So the result is 7/2. The problem is that there is no 7/2, there is a split. We can change this to a split because the denominator is larger than the denominator. The way to change it, I have explained everything yesterday in Basic TU, but it's okay, I'll explain it again so you remember. 7/2 means 7 divided by 2.

How many times 2 is close to 7? That's 3. 3 times 2 is 6. 7 minus 6 is 1. That means the combination is 3 1 per 2. So the answer is section B. How about it, friends?

I understand, until here, those who understand, just say it in their hearts. If anyone wants to ask, please write it in the comments column so that there is no closing that wants to ask. For those who want to ask specifically, which one do you want to ask next? Which one do you not understand so that I can immediately explain. Don't just say, "I'm still confused, which one is next?"

Why not make it 5/5? Which one is 5/5? If 5/5 is equal to 1, not equal to 5. The second way is later in another issue. This means that the first way is to reduce the number of rounds with division.

I will make a disclaimer first, I am a bit long in writing, because I am explaining the position to you. If I write my version when I work, you will be confused because if I work, it's only two steps, it's done, but here I write it really well and complete so that you guys understand.

If you didn't join yesterday, just join first, guys. You can see the basic TU recording later. Because I can't repeat the previous meeting, okay? "Coach, I'll use another way, the results are the same." Sure, sure. "Kak, should I replace it with Kali?" Yes, I explained this in the basic TU yesterday. Just take a look later.

That's what is defined as a way to use it anytime. Later I will explain when the first and second ways will be effective. Just be patient. Don't spam it, friends. So it's a cover for people's questions. If you write your questions many times, especially if you use caps lock, how is it?

Just relax, ask as usual. Those who want to write it continuously, don't write it continuously many times, it really disturbs the comments column. So I press it again, I press it again for the use of the comments column on Zoom, please help.

the comments column on Zoom is only intended for questions about the issue. Okay, because our class is crowded, so we need cooperation from friends. Those who want to continue, please don't write it down. Unless the class is quiet, it's okay.

I know when I have to continue, so you guys maximize the use of the comment column to ask questions. Because if it's like this, I just close the comment column if it's just spam, so it's a loss, I can't ask anyone else. How do I differentiate 5 minus 1 divided by 2 is equal to 4, 4,

2 per 2, this is already a next level if you do it like that. Okay, let's continue first, friends. Later it will be more understandable if you have watched the basic Tiu's recital. Most of the people who ask here are those who didn't attend yesterday's meeting, I think. It's hard to understand if you don't attend basic Tiu. Okay, now for question number 2, please choose the answer.

Why did you say 5/1 should be 10/2? So that the name is the same. If you reduce 5/1 to 3/2, it can't be because the name is different. Okay, let's see first. 73% choose section B. Okay, okay. Friends on YouTube, this is just a comment, the answer is all wrong. There is no other. Okay friends, number 2.

The result of all focus, the result of 0.6 multiplied by 1/2 is reduced by 3/4 divided by 1/2, remember this is a mixed operation, friends, so there is a time

kurang bagi. Okay, so we have to do it one time first, friends, and share. So I block like this, kurang is done last. Now don't forget to make a choice, the choice is all division, friends, division of mixture and normal division. Well, it means we should convert all of this into division.

Okay, so that the final result is also divided. Now, yesterday I have taught how to change the decimal to a division. So, if 0.6 we want to change it to a division, this is one number behind the comma, which means this is per 10. Then the denominator is 6. Okay, multiplied by 1 per 2, minus 1.

3 divided by 4 divided by 2, because this is the division of division, we change it into a fraction, then the two are reversed into 2 divided by 1 or 2 is also okay, it's the same. Okay, now we work on the fraction, so we can draw the cross section, I have taught this in the basic theory yesterday.

So, we can divide 6 by 2. How many can each be divided? Each can be divided by 2. 2 divided by 2 is 1. 6 divided by 2 is 3.

10 divided by 1 can't be, it's stuck there. Now, if this one, which we can subtract, is 2 divided by 4. Each one divided by 2, 2 divided by 2, 1, 4 divided by 2, 2. Okay, now we write the result. It means that the one above, 3 multiplied by 1 is 3, multiplied by 10 multiplied by 1 is 10. Reduced by 3 multiplied by 1,

3, 2 x 1, 2. Okay? So, 3 x 10, minus 3 x 2. Wait a minute.

Yesterday I also taught how to reduce the division of friends. This is a different name. So we have to match. This can be used to divide the value that I explained yesterday. So 10 to 2. KPK from 10 to 2 is 10. So we change everything to 10.

2 if you want to make it 10, how many times is it, friends? times 5, which means this is also times 5, this doesn't have to be changed again because it's already times 10, so we just write it over and then this 3 times 5, 15, okay? So this is the same name, we just need to subtract the denominator, 3 minus 15

The reduction is smaller, so negative 12/10. This can be simplified, friends. Each is divided by 2. Each divided by 2, meaning 12 divided by 2 is 6, 10 divided by 2 is 5. So negative 6/5.

The denominator is larger than the denominator and 6 divided by 5 is not here, which means we have to change it into a division of the mixture. 6 divided by 5, this can actually be in the head, friends. 6 divided by 5 means 1 multiplied by 5. So the division of the mixture is 1, from here it reads 1, 1,

per 5 but there is a negative, remember the negative, so negative 1 1 per 5 so the answer is section B, now I wrote it for a long time, friends, if it's done by yourself, it's

this step is just skip, friends, we just change it to 15/10 and then simplify it but once again because I am in the position to explain to my friends so I write it in full so that you guys understand later if you have worked on the issue more and more you work on the issue the less your notes are okay, those who understand

Just say it in your place, "I understand coach" don't have to type it first because it's crowded. Now I open the comments column for those who want to ask. Those who want to ask, please specify where you don't understand it. Even if someone wants to ask, friends, friends on YouTube, is the division still replaced by division? Always if the division is divided.

"Kak, my way is different, 6/10 is not me, 6/10, 12/10 is not me, simplify it." You can also simplify it at the end, that means. The negative is forgotten. Okay. "Kak, sorry, the first one, how can 6/10 be?" It is simplified, each is divided by 2, so it is 6/10. "If the choice is decimal, does it mean that everything is replaced by decimal?" Not really, I'll show you later if there is a decimal, then the choice is decimal, how to do it.

The second step, if it's not simplified, it's okay, does it affect if the division is bigger? If you don't simplify it here, then you immediately change it to a combination division, it can also be, but at the end you will still simplify the division, because there is no 10 here, it remains 5. Where did the minus come from? 3 minus 15, the 3 is smaller, so it's negative. What else?

Kak, the 0.6 is included in the division? No, it only changes the decimal division to the usual division. Why can't it be reduced directly if the names are not the same? You follow me on TikTok.

There are various questions that are often asked in mathematics. Why is the term "separation" must be equated? That's a long proof, friends. But I have explained on my TikTok, if you have time, you can see it later. 12:10 can be simplified directly, just by looking, so you don't have to work twice. If you can, just do it.

It's the same if you convert it into a split mixture, it becomes 1 2/10. 2/10 you simplify again to 5, so you still simplify the ends, it's still simplifying. It's not 6/10, it's 6/5. Okay, let's continue, friends. Let's continue to number 3, please choose the answer.

Usually, the CPNS test is always the simplest choice in IRGA, so try to make it as simple as possible. Okay, friends on YouTube have answered. The answer is part C, he said. Now, only 45% of the people on Zoom chose part C. Okay, why only 45%?

What's there? What's there? This is really easy, friends. Let's see. Pay attention to everything carefully. Later the painting will continue. Pay attention first, okay?

5 divided by 6 is reduced by 1/3 plus 4/9 times 3/2 divided by 2/3 Okay, friends The choice is the round number and the division So we just change everything to division, yes, it turns out that all of them are divided, so we just work on it The most we change here is only this division, right? This division we change to the division

Then we return 2/3 to 3/2. Okay, I'll just write it again so it's clear. So 5/6 - 1/3 + 4/9 * 3/2 * 2/3 = 3/2. Okay, can you guys?

Okay?

If we can sort out the fractions, which one can we sort out first? 9 and 3 are okay, each divided by 3. Remember to memorize the fractions 1 to 10. Next is the division. If you don't memorize the fractions, you can't go anywhere, friends. So you have to memorize the fractions. 9 and 3, each divided by 3. 3 divided by 3 is 1, 9 divided by 3 is 3.

Okay, which one is it again? 3 with 3 here is possible, because everything is a multiplication. So this calculation is still wrong. 3 with 3, each divided by 3. 3 divided by 3 is 1, 3 divided by 3 is 1. Now, 4 with 2, each divided by 2. 2 divided by 2 is 1, 4 divided by 2 is 2.

Okay, which one is 2 with 2 here? It can be, so each one divides 2, 2 divides 2, 1, 2 divides 2, 1. Okay, now we just have to work 5 divided by 6 is reduced by 1 divided by 3. This is the result, be careful, friends.

This is the result of 1. 1 x 1 = 1. 1 x 1 = 1. 1 x 1 = 1. 1 x 1 = 1. 1 x 1 = 1. How much is 1 x 1?

One. Okay? So I never teach the participants of Bimbel Viracun to cut it all out, but each one is divided into how many. So that there is no misunderstanding about the cuts like this, it is expected to be finished. Yes, even though there is only one left. Alhamdulillah, I'm sorry.

So this is 1/3, we change it to 6, so that the name is the same, so it's only x2, this is also x2. So here 5/6 is reduced by 2, 1 x 2 = 2, 3 x 2 = 6, 2/6 plus this is the result 1.

Okay, 5 divided by 6 is equal to 3 divided by 6 plus 1. 3 divided by 6 can be simplified, each divided by 3. 3 divided by 3 is 1, 6 divided by 3 is 2. So, 1 divided by 2 plus 1 is equal to 1 divided by 2. Is there 1 divided by 2?

So we change it to a regular split. This is a bit less linear, usually it's a direct split. But it's okay, we change it to a regular split, 2 times 1, 2 plus 1, 3. So it's 3 per 2. So the answer is part C. Okay, friends, you know where the mistake is? Please ask.

Which section is less clear? Friends on YouTube, please comment on which section is less clear. I'll check the first section. Yes, it's dangerous, friends. It's always thought of all this time because many people make content that is crumpled, crumpled, crumpled. Even though I don't understand what the essence of crumpling is actually for separation. That's why it's so important to learn the concept.

That's multiplied by 5 so that the name is the same. Why is the last number that is divided multiplied? I explained this many times earlier. If the division is divided by a fraction, we change it to a fraction. So it's easy to calculate. Because if it's divided directly, it's difficult. If it's divided. Yes. I forgot to add 1, so the answer is B. Okay.

I've shared the previous question, guys. "I have a different way but the result is the same." Sure, sure. If the result is the same, it means you're right. "I use 6/6 method." Oh, you make one 6/6. It's okay, you can do it.

I'm sorry, I can't repeat the order If you want to repeat the order, you can do it again Because I really have been eager to explain the order So if you go check, you will be repeated in the order Because we have 15 questions that we have to discuss 3/6 even though the number can still be sorted 3/6 is the concept is simplified Not operated with one, okay?

Okay, on average, the problem is all about basic TU, why 1/3 times 2, it's all explained in a long time in basic TU, friends, it's impossible for me to explain it again here because the explanation is indeed long, later just watch the recording again, okay, let's continue with question number 4

One is very entangled, sis. That's why it's shown so that you guys can be entangled here. Don't be entangled later in the real questions in the CVNS test. Okay, please choose the answer for question number 4, friends. Okay.

Only 61% choose C, less than 80% It shows that the struggle is working, friends, it's okay You are forced to struggle here so that the learning is really thinking, friends Okay, question number 4, question number 4

Still with the same model, so the model of the question in the CPNS test is like this, friends. If you want to know who has never tested CPNS, the model is like this. So we have a lot of questions like this. Then the choice of the answer is division. So we work, it's still round with division, there will be a decimal later, calm down.

This is a multiplication, but the multiplication is a combination of fractions, so we change it first, friends. So, the usual fraction is 5 minus 2 divided by 3 times, this we change to the usual fraction, 2 times 2 is 4, 4 plus 1 is 5, per, follow here, per 2, plus 8 divided by 3 is

Divide by 2, this is the division of division, friends. Because there is a division involved here. Well, if divided by 2, it's the same as divided by 2 times 1. So if it's changed to times, we're back to times 1 times 2. Okay?

Now we work on the times, friends, which are sorted first. Now this is 2 with 2, each divided by 2, 2 divided by 2 is 1, 2 divided by 2 is 1.

Then this one again, the multiplication, 8 with 2 can be. 3 with 5 can't be. So this is 8 with 2, each divided by 2. 2 divided by 2 is 1. 8 divided by 2 is 4. 1 with 3 is already stuck, can't be anymore. So that's it, that's the result. Now we multiply, the other one write it again. 5 minus, we multiply this, 1 multiplied by 5 is 5.

3 times 1 is 3. Okay? Add 4 times 1 is 4. 3 times 1 is 3. Well, coincidentally, the division is the same. So, we just operate it. Just write 5 again. So, 5 is reduced. Ah, wait. This is a precautionary measure, friends.

This is not 5 plus 4. Okay, I repeat, this is not 5 plus 4. But this is negative 5 plus 4. So negative 5 plus 4 is equal to negative 1, 5 debt.

5 debts plus 4 money, so there's 1 negative 1/3, okay?

Maybe some of you are still confused, this is different. Different if for example like this, 5 + 5/3 + 4/3. If the writing is like this, the result is 5 + 9/3.

Okay, friends, because it's positive here, so the calculation is 5 + 4, but if it's less here, it means the calculation is negative. Can you see the difference, friends? Yes, it means that this is up to here.

5 minus 1 divided by 3. 5 minus 1 divided by 3, how much? You can use the method earlier, method 1. So, 5 times 3, 15. Divided by 3, minus 1 divided by 3. Or, the second method. The second method, reduce the number of circles with division. So, 5 minus 1 divided by 3.

5 of these can be changed to 4 plus 1. 5 equals 4 plus 1, right? Right, right. Reduced by 1 per 3. But to make it easier, I change this one to a fraction of 3. I change the first one to 3 per 3.

Why? So that the term is the same. If it's 1/4 here, I change 1 to 4/4. If it's 1/5 here, I change 1 to 5/5. Follow this one, so that the term is the same. So 3/3 - 1/3 = 4 + 2/3 or 4 2/3.

Okay, so the answer is 4 2/3 The answer is part C Okay, maybe there is a question when is the first effective way and when is the second effective way Actually, all of them are effective, friends But, what, honey? Before the cherry, before the tea Oh, it's below, below the sofa Okay

Maybe someone is asking, "When do we use the first method and when do we use the second method?" Well, if the first method is the least, for example, I give an example, I give two examples here. If it's like this, 6 - 3/17

6 minus 3 divided by 17. The first way will be a bit difficult. Why? Because if you multiply 17 by 6, 17 divided by 6 will be

The number is very large, isn't it friends? 17 times 6, not yet simplifying it at the end. Well, if you use the second method, you just have to change it to 5 plus 1, but you change one to 17 per 17, so it's reduced by 3 per 17.

The result is 5, 17 minus 3 is 14 per 17. Without having to multiply. The first effective way at 6 minus 17 per 4.

If the second way is more effective when the round number, the first way, when reducing the round number with the fraction number whose denominator is larger.

So this concept is actually reduced by the number of mixed fractions Because this is a bigger number, friends So this becomes 4 times 6, 24 per 4, minus 17 per 4 This is better, one way 24 minus 17, this becomes 7 per 4 Okay, can you guys?

Kak, I used the same name first, so I'm confused. Which one do you use the same name? This one is the same name. Okay, is there anyone who wants to ask? Friends, please type directly what you want to ask. This is the second way, this is the first way. Amin doesn't know, just write the other one. I don't know how to write the first one.

Yes, tomorrow. 3/3 from where? From 1. This 5 is changed to 4 + 1. But I make 1 3/3 so that it can be operated with 1/3. I'm still confused about 5 9/3. Which one is 5 9/3?

Oh, this one. This is the sign that I explained earlier. If this is negative, the calculation is negative 5. If this is positive, the calculation is 5. Yes, one way is also effective, but if the denominator is big, the number becomes large. 5 is reduced by 1/3 from which one? Negative 5 plus 4. Negative 5 plus 4 is negative 1.

The ones who don't understand seem to not follow the round number yesterday. The reduction of the round number that has a negative. Does it follow? If it is changed to 5 per 1, it can be, but it doesn't immediately change to the number of mixed fractions. I rarely change it to 5 per 1, friends. Because in my opinion it is complicated. But if you think it's not complicated, it's okay. For the second way, is it mandatory to reduce one?

That's not what I mean, this is to change directly into a mixture, friends. One is that we change it to 3/3 so that it can be operated with 1/3, that simple. Most of the confused ones who just joined today.

So I didn't join the basic Tiu yesterday, so I'm sure I've been a disclaimer from the beginning, you must be struggling to understand this if you don't join the basic Tiu. So just follow it, later the basic Tiu will be re-recorded.

4 plus 2 divided by 3 is not different from 4 divided by 2 divided by 3, right? This has been explained yesterday in Basic Tiu about the mixing of the ingredients. So please, the PR only watches Basic Tiu. Your problem is only there. If I see from the questions that are confusing here, the problem is usually only because Basic Tiu didn't join yesterday. So...

That's it, the BPR, later the basic Tiu will be repeated, then back to this recording. Okay, let's go to question number five. Please choose the answer, not work on it. Later it will be repeated again, how to reduce it, later there will be another question like that. Okay.

still 60% 61% who choose the C section, friends on YouTube always compact, Bang, answer the same answer, just follow along, okay, let's move on to number 5

Well, this number 5 is different from the previous questions. In the previous questions, the multiple choice is a division. Now, the multiple choice is a decimal. So, how do we do it, friends? I have some suggestions, for example, the multiple choice is a decimal. The first one,

I don't recommend to change everything into decimal numbers. I really don't recommend to change everything into decimal numbers. Especially if there is a multiplication and division operation. Because working on decimal numbers with

The division and division operation is very complicated, in my opinion, it is very complicated. So what? Well, for me, friends, for the division and division operation, I changed it into division. What I didn't change into division was the multiplication operation.

decimal number that I don't change into a fraction, yes, decimal that is related to the addition and subtraction only, but if the multiplication and division I change it into a fraction so that it's easy for me to work, okay, so this is the same as 2.4, I still write 2.4, yes, later I'll see if I have to change the fraction or not, then add 1 per 2

times 50% we change it into a fraction, 50% is equal to how much? 1/2, friends, 50% half of it, so 1/2 times 1/2 plus, because this is a division, I change 1.2 into a fraction, one number behind the comma means 12/10.

For me, I change it into times, then I return the 3 times 2 to 2 times 3. Okay? Now, we just have to do this first, the times first, friends.

One by two, none of these can be divided, because all of them are in a row. One by one, two by two, are in a row. So if none of these can be divided like this, then it's already a denominator times a denominator, a denominator times a denominator. Now, if this one, none of these can be divided. There are 10 by 2, each by 2, 2 by 2 is 1, 10 divided by 2 is 5.

12 with 3, each can be divided by 3. 3 divided by 3 is 1, 12 divided by 3 is 4. Okay, so this is equal to 2,4 plus 1 times 1, 1, 2 times 2, 4, plus 4 times 1, 4.

5 times 1 is 5. So, 1/4 plus 4/5. Well, the names are different, so we have to match the names. Well, yesterday at BSTU, I have explained that matching the names can be done using the same KPK value as yesterday, or you can also use the times. Well, I recommend using the times because the names are small, guys.

So if we use the cross, 2.4 plus 1 times 5 is 5 plus 4 times 4 is 16 times 4 times 5 is 20. Okay? So 2.4 plus, ah, wait. I will show you this using a split, but...

it seems that it's really easy to use decimals, so this is one quarter added 4/5 Now friends who are familiar with the division, yes, one quarter is how much the decimal is one quarter is equal to 0.25 okay if 4/5 4/5 is equal to

0.8 yes friends so one fourth is 0.25 4/5 is 0.8 so friends can just add it here so 0.25 + 0.8 because it is related to

The choice is decimal. Now, how to sum up decimal numbers? Remember, sum up decimal numbers is not the same as sum up round numbers. The way is to straighten the comma. So, 2.4 plus 0.25, this comma must be straight, plus 0.8.

Now, this is just added all friends, so 5, 4 + 2 = 6, 6 + 8 = 14, this is 3, the comma is here, which means 3.45, that's it.

For those who use a split, you can also, I want to show if I continue using the split, for example, you don't know, you should know, because it has been told that 1/4 is 0.25 and 4/5 is 0.8. That's it, please, if anyone wants to ask, try using the split earlier, okay, okay.

I canceled using the fraction, because suddenly I remembered, 1/4 is 0.25, 4/5 is 0.8, so I canceled using the fraction. If it's not as good as me, what if I continue using the fraction? Okay, no problem. I write it here. So, 2,

2.4 plus, I just multiplied it, friends, you can see in the basic TU 1 times 5, 5, 4 times 4, 16, per 4 times 5, 20. So, this is the result, 5 plus 16, that's 21, so 2.4

plus 21/20. The problem is, 21/20, what is the decimal? It's easy, guys. So, this decimal, remember, decimal is the ratio of the easiest to convert decimal from decimal to decimal when it's 10, 100, 1000, and so on. This is

It's really easy to change it into a decimal. So we just have to find the fraction that is the same value as 21/20. We change 20 to 10, 100, or 1000. 10 is divided by 2 each, friends. This can be divided by 2 each. But 21 can't be divided by 2. So what? If it can't be 10, we make it 100. Okay?

So, we make it 100. How? Well, we multiply it by 5. Same as the previous value division. So, this is multiplied by 5, and this is multiplied by 5. So, this is 2.4 plus 21. Yes, that's right. 21 multiplied by 5, 5 multiplied by 1 is 5, 5 multiplied by 2 is 10. 105 multiplied by 20 multiplied by 5 is 100.

So 105 divided by 100, changed to decimal, so 2.4 is added. Per 100 is two numbers behind the comma, so 105 becomes 1.05. This is the same, the result becomes 3.45. Okay, friends?

It might be a bit more complicated if it's divided, but if you understand the way, believe me, it's not that complicated. Okay? But it's easier if you already know the decimal. You should already know because I've told you here. "Kak, did you change the division to decimal yesterday? I don't think so." Oh, yeah, I didn't explain it yesterday. Okay, I'll explain a little bit here.

I didn't explain it yesterday, okay, so I'll explain a little bit how to change the decimal, how to change the division into a decimal, so for example, one fourth we want to make it a decimal,

There are two ways, you can use the usual division method, one divided by four, or this can be directed to be per 10 or per 100. This 10 can't be, so we direct it to be 100. 4 times what equals 100? times 25. So this is 25 per 100. So the decimal is 0.25.

For example, 2/50, this is a decimal number, so we just multiply it by how much? So that it becomes 100 times 2, so 2 times 2 is 4, 50 times 2 is 100, so this is 0, 2 numbers behind the comma means 0.04. Can you guys?

make it 100, 10, or 1000, whichever you can. I use this, Kak, 2.4 x 0.5 x 0.5, okay, okay, okay. 1.2 divided by 1.5, okay, okay. Because 1.2 divided by 1.5, you divide it by 1.2 divided by 1.5, how do you do that? Later, if you test CPNS, you give paper for the exam,

How can we make it easier for us to change 1.2, 1.2 so the division is 12/10, right? The test system will be changed later, who said there was no official announcement? You can use the poro-gapit, okay, let's continue, friends, I think I'm too late at number 5.

we continue to number 6 because in the next numbers we will continue to repeat this skill so that you guys are used to it okay now please choose the answer 1 hour 5 questions yes because I explained to more than 1000 people, Ms. Mulia, if I do it myself

15 questions, 20 minutes is enough, 15 minutes is enough. Okay, this is quite a lot of people who answered. 71% choose section C. Let's go to number 6. Okay, 71% choose section C. Let's see, friends. Everyone pay attention.

4 divided by 2 is minus 0.8 multiplied by 40% plus 1.2. The choice is decimal again. So, we change this division, friends. The other one, oh, 4.5. Remember, 4.5 is equal to 4.5. Okay, so we just change this to 4.5.

4.5 minus 0.8 is 8 per 10. Then 40% is equal to 40 per 100. But if the zero is corrected, it can be 4 per 10. Or to simplify it again, it can be 2 per 5. But I only use 4 per 10. 4 per 10, if it's reversed,

This becomes 10 divided by 4, plus 1.2. Now, we just need to divide by 10, and 10, each divided by 10, 8 divided by 4, that's 2. So, the result is 4.5, minus, this result is 2 times 1, 2, divided by 1, 2, minus 2, plus 1.2.

4.5 minus 2 is 2.5, friends. 2.5 plus 1.2 is 3.7. This can be directly in your head. If you can't, it's okay. Write it again, it's okay. So the answer is part C. This is easy, friends. There are questions up to here. Please.

3 can't be divided by 10, by 100. Yes, that's why we use the usual division if it can't be directed to 10, 100, or 1000. 4.5 from where, Kak? You know that 1/2 is equal to 0.5, right? 4/2 is read as 4.5. 4.5 is equal to 4.5, friends. 4/10 from where? This one.

I have taught you how to change the percentage and decimal of the division, it's in Basic.TO. So you can see the recording in Basic.TO. If you can make all the decimal in the book, it's also possible. The important thing is if you know that 40% is equal to 0.4. So 0.8 divided by 0.4 is 2. It can also be like that.

3.7 from where? From summing everything up. Try to sum it up. Try, try, try. Don't just look. Try it. If you're confused, I'll try it. Was the result 3.7? That's how you learn, friends.

I make all the usual breaks first, in your opinion, if you change to the usual break first, how fast is it compared to this? So here, we are discussing, friends, so you can compare, oh, I think I'm faster, I think I'm faster like this. Is 10/4 not simplified anymore? No, because I have simplified it, it is automatically simplified.

Actually, you can't skip it, so you won't get confused. Yes, I've been told from the beginning. Anyway, don't skip it if I explain it. Because you will be confused yourself if you skip it.

Yes, Brigitta said, guys, this seems like most of the questions were answered in yesterday's session. Yes, because yesterday, the first one yesterday, I designed it to answer all the confusion that is here, friends. So if you didn't join yesterday, it's a bit difficult. That's why I said from the beginning, just follow it, you'll see the recording again, okay? How fast is the polling? I opened it for more than a minute, that's the polling. Okay.

Yes, that's all the problem, the question is only about Basic Tiu. If you watch the recording of Basic Tiu until the end, all your questions will be answered, friends. Okay, let's continue, we're only number 6, there are 15 numbers. So that we don't get bored, especially those who are in the wait, poor. Okay, please choose the answer, number 7. Okay.

Now, let's just discuss question number 7, guys. 65% choose section D. Okay, good. Question number 7. Now, this is a decimal choice. So, we change what must be changed. It means that what is changed is only this. The rest we just leave it as it is. Okay, so this is 2.4 plus 5 times 2.

multiplied by 20%. 20%, remember the basic TU yesterday, 20% is equal to 1 per 5. So multiplied by 1 per 5, plus

1.5 we change to a normal fraction, so 15/10 because one number behind the comma then this is a division, so we change it into times, then 3/5, back to 5/3, minus 0.3 okay, we work on the times first, this is a bracket, 5 with 5, each divided by 5, 5 divided by 5, 1, 5 divided by 5, 1

Nah, 15 dengan 3, masing-masing bagi 3, 3 bagi 3, 1, 15 dibagi 3, itu 5. 5 dengan 10, masing-masing bagi 5, 5 bagi 5, 1, 10 bagi 5, 2. Oke, nggak ada lagi yang bisa dicoret. Jadi...

2.4 plus 1 times 1, 1, 2 times 1, 2, 1 by 2 plus 5 times 1, 5, this is 5 by 2 minus 0.3. Okay, coincidentally the name is the same, so just 2 times

2.4 plus 1 plus 5 is 6, so 6 divided by 2 is minus 0.3. So this is the result, 2.4 plus 6 divided by 2 is 3, minus 0.3. Who can directly sum up,

It's better again, 2.4 plus 3 is 5.4. 5.4 minus 0.3 is 5.1. So the answer is 5.1. You can't just sum it up using an orderly sum. So 2.4 plus 3, put the 3 here. Then 0.3, oh this is added first.

This is added first, so this is 4, this is 5. Reduced by 0.3 means we are reduced. 4 minus 3 is 1, 5 is reduced by 0.5, so it's 5.1. Okay, friends, please if anyone wants to ask. If so, I will write the answer right away, friends. It's usually the second step if it's on paper.

Have you ever tested CPNS Nurul Fitri? Is this your first time or what? I'm sorry I'm in a hurry because there's a 0.3 after the test. Okay. There's no more questions about the size or rank, guys. If you're still confused about 20%, go back to basic TU. Okay? After the multiplication and division, I changed everything to what? To decimal. Where's 3 from? 6 divided by 2? 6 divided by 2 is 3.

Per is the same as division, yes. It means for the division, the division is the same as division. 20%, why not 10/2? Hey, where did you get the sum from? 20% is equal to 20/100, each is simplified, divided by 20, you get 1/5. Sis, 1.5 is 15/10, but if I make it 3/2, okay.

1.5 is the same as 15/10, it can also be 3/2, yes, the same. The pattern is seen from the multiple choice. Yes, the multiple choice becomes our pattern, what should we do? So if the multiple choice is decimal, I don't change it to a fraction, unless it is a partial and partial operation. 5/2 and 3/5 are directly decimals, okay. 5/2 and 3/5

Yes, you can, but if you convert it into decimal, then if you multiply 20%, then you divide it by 3/5, how do you do it? Try to explain. If 3/5 you convert it into decimal, how do you divide it by 1.5? How do you do it? If I prefer to convert it into a fraction, because it's easier to do.

If 5.1 is changed to a fraction, why do you want to change it to a fraction while 5.1 is already there, the answer is the same as changing the decimal to a fraction. Okay, let's continue to number 8, friends. Please choose the answer.

Why 20% is not made 20 per 100? It's the same, but 1 per 5 is simpler. The simple form of 20 per 100 is 1 per 5. Each one is divided by 20. Okay, it's been a minute.

Alim, Anissa, Rhea, all answer E on Youtube except Suci answer D Coach Vira is very patient, patient coach, yes I'm used to it, this has often happened Okay friends, number 8

This is still the same, so there are a lot of questions about the 2024 CPNS, the choice of the multiple is decimal, so I have a lot of decimal choices. Let's all focus on the screen first. The result of 2.4 plus 1.5 is 20% minus 4.5.

Okay, friends, because this is times, I change it to a fraction, remember 20% is equal to 1 per 5. Okay, so 2.4 plus 1 per 5 minus 1 per 5 times 4 per 5. Okay?

Don't ever work 1/5 minus 1/5 equals 0. Don't. Because there is a multiplication here. So we have to work on the multiplication first. Don't go too far. So this becomes 2.4 plus 1/5. There is nothing that can be sorted. So we multiply the denominator by the denominator, the denominator by the denominator.

minus 1 times 4, 4, 5 times 5, 25. Okay, so we just have to reduce this, but the problem is the name is different, no problem, we will equate. This is 25, KPK from 5 to 25 is 25. So we just have to multiply 5, this is also multiplied by 5.

This is 2.4 plus 1 times 5, 5. Which is smooth, don't write like this again, friends. You can think in your mind. 1 times 5, 5. So 5 minus 4, 1. So 1 times, this is the same 25. So it's fast. Don't write too much that it's broken. But because I'm teaching, so I write it broken, friends.

1/25, how much is the division? Remember to change the division into decimal, we direct 25 to 100, friends. We multiply 4, so it becomes 100. So this is 1 times 4, 4 times 25 times 4 is 100. 4 times 100, what is the decimal number, friends?

Two numbers behind the comma means 0.04 So 2.4 minus 0.04 Eh 0.0 This is not 0.4 0.04 Because two numbers behind the comma per 100 So 2.4 plus 0.04 So this is

2.44, but for those who are confused, I'll write it again, it's okay. So 0.04, this is added, so it's 442. So the result is 2.4. The answer is part E. Can you guys? Please ask if there is anything that is touching your heart. It doesn't appear.

I used the "porogapit" to answer, sis. Sis, as long as... The CPNS issue is planned so that you guys can answer it quickly, friends. So it's rare that the issue is made so that you guys are confused. Actually, everything can be made simple if you understand the way. Sis, I've been asking about the division and decimal multiplication since before it was discussed. I discussed it yesterday.

Decimals and percentages. If it's decimal and percentage, I like to change it to percentages. I have explained the concept of multiplication and division of percentages yesterday. So, it's all in the basic TIO.

1/25 from here, this is changed to 5/25, 5/25 is reduced to 4/25, 1/25, it starts to go smoothly, okay, I can also coach, it's okay, if you become a decimal, 1/5 is 0.2, then 20% is also 0.2 times 4/5 is 0.8, so maybe the PR is only in

0.2 times 0.8 okay okay you are still confused one fifth equal to five but why one twenty-five see the concept of a value gap in the basic tiu that you met yesterday all your questions will be answered there how can it be one twenty-five, it has been operated with here so five minus four is one I skip

I skipped one step and I was confused. This is one step that I didn't write earlier. I just explained it. If you don't have to write this because of the length. This is 5/25 - 4/25. So it can be 1/25.

If I miss all of your questions, friends, three days, three nights, we're not done here. So let's just continue to the next question. Because actually all of your questions are in the basic Q, the answer. Okay, please choose the answer. Not to be worked on, but to choose the answer.

Okay, 70% choose C, okay, it means it's a bit easy, because 70% of the answers are correct. Okay, friends, pay attention to all of them. 1.5 plus 2 divided by 3 times 30%, okay, plus 6 divided by 5, divided by 3 divided by 2, minus 1.0. Okay, this is the choice, there is a decimal, there is a division.

So how do you do it, sis? You can keep it decimal, or you can change it to a fraction. It will all bring you to the same place. So for those who are changed to fractions, everyone can do it, for some people, they can do it too. Because there are two options here, the answer. So, for example, I

I didn't change the decimal, so 1.5 plus 2 divided by 3 times, remember 30% is how much is the division? 30% is equal to 1 per 3. Okay, so 2 divided by 3 times 1 per 3 plus 6 divided by 5, we divide it into times, then reverse it.

times 2 divided by 3 is minus 1.0, which is equal to 1, so you don't have to be confused with the 0.0. Now we work on the times, so this is okay, there is no one who can be corrected, so just multiply it. Then this is 6 and 3, each can be divided by 3, 3 divided by 3 is 1, 6 divided by 3 is 2, okay?

Am I wrong? 2/3, this is 4/5, wait a minute. Oh this is wrong, I'm wrong, 30% 1/3, oh wrong, wrong, wrong. Not 30% 1/3, I'm sorry. If 1/3 is the same as, I'm sorry.

1 per 3 is equal to 33.33%. Sorry. 33.33% is 1 per 3. If 30% is equal to 30 per 100. Or you can subtract the 0 from 1, so it's 3 per 10. Okay. Sorry. So here it's 3 per 10.

So we can divide 3 by 3, 3 by 3 is 1, 3 by 3 is 1. 2 by 10, each of them is divided by 2, 2 divided by 2 is 1, 10 divided by 2 is 5. Okay, so we can write 1,5 plus 1 times 1 is 1, 1 times 5 is 5. Plus 2 times 2 is 4.

5 times 1 is 5. Okay, the name is the same, minus 1. So, this is 1,5 plus 1 plus 4, 5, guys. So, 5 times 5 is the same as 1, minus 1. So, this is the result, 1,5, part C. Okay, you can explain if there is anything you want to ask.

Sorry, the 3/10, I thought it was 33.3%, finally I'm right, but the poly is not on my cellphone, okay, it seems that there is no problem with this issue, friends, how about 4/5, 4/5 is the result of the sketching, this is 2 times 2 4 5 times 1 5

Yes, sorry, it was a three. Where is one from? From the question, 1.0 is one. This one, this is one. One plus four is five, five times five is equal to one. Oh my God, Robby. Okay, I'll write the complete list if so.

This is 1.5 plus 1 plus 4 is 5, so 5 divided by 5 is 1. So 1 divided by 5 is 1, so 1 divided by 1 is 1. But this is written in length, friends. So I just added 1 plus 4 is 5, 5 divided by 5 is 1.

1.5 plus 1 minus 1, 1.5. It can't be simplified by 3 per 10. Okay. If you change it to all, the result will be the same. There is no difference. Still get 1.5. Okay, let's continue. Number 10. Oh, I'm only number 10 again. I'm sorry if the time is a bit slow later, friends.

Not memorized but understood, the way to change it, used to the problem, working on the problem, it automatically comes to itself. Yes, there will be PR and PES again, just calm down. Okay, friends, only 52% chose the part, why? What's wrong with the 10th question?

Oh, there's this again, okay, okay. Everyone pay attention to number 10 as well as possible, okay, let's start.

50 minus 3 divided by 4 plus 1 divided by 2, this is in the box, so we can work on it first. Although it is a sum, but because it is in the box, it is the winner, it can be worked on. 3 divided by 4 plus 1 divided by 2, 1 divided by 2 can be changed to 4. The way is to multiply it by 2 divided by 2. This becomes 2 divided by 4. So 3 divided by 4.

plus 2 divided by 4, I write it here so it's not too long, it's the same as 5 divided by 4. So 50 minus 5 divided by 4, this is changed to times, 20% is the same as 1 divided by 5. So if you reverse it, it's times 5 divided by 1. Now,

This is the multiplication, there is no one who can be sorted, so we multiply the denominator by the denominator, the denominator by the denominator. So 50 minus 25 per 4. This can be used in one way, it can be used in the other way.

Oh, this can be used as a way 1 or it can also change 25 into a split mixture. But let's try to use the way 1 first. So this is multiplied by 4 multiplied by 50, how much? 200, friends. So 200 per 4. So 50 is changed to 200 per 4, minus 25 per 4.

200 minus 25 is equal to 175 divided by 4. 175 divided by 4, we change it into a split mixture. 17 first. So how many times 4 is close to 17? 4, 4 times 4 is 16.

Then this goes down 15. Now 15 is still bigger than 4. So we continue. How many times 4 is close to 15? 3. So it's 43. So 3 times 4 is 12. This is 5 minus 2 is 3. So the result is 43 3 per 4. So I recommend more

Cara satu kalau kita mengurangkan bilangan bulat dengan pecahan yang lebih besar pembilangnya. Jadi, lima empat puluh tiga, tiga per empat. Jawabannya bagian D. Jadi, kalau menjumlahkan bilangan bulat dengan pecahan yang lebih besar penyebutnya pakai cara satu saja. Tapi, kalau misalkan...

he's like this, I'll give you an example of how to do it, for example, for example, because 50 is reduced by 4 per 25, this is better to use the second way, so we change 50 to 49 plus 1,

But we make 1 25/25 Then minus 4/25 So this is 49 25 minus 4 is 21 So 2 49 21/25 That's the difference Okay, so if

The denominator is bigger, just use the first way, but if the denominator is smaller, just use the second way. Any questions so far, friends? Do you know where the mistake is? My coach, you chose it with feelings, it turns out to be true. Okay, how about 200/4? That's the one that used the first way, which changed 50 to a split.

From 4 times 50. If 25 divided by 4 is changed to 5 5 divided by 4. Why is it 5 5 divided by 4? 6 1 divided by 4. If 25 divided by 4 is changed to 6 1 divided by 4, it's okay too. But you have to be careful with the minus sign. If the result is the same, it means your method is correct. Sis, 5 divided by 1, can it be 5? Yes, it can.

I only write it 5/1 so you can see it, if that's me, I'll go back later, many are confused again. That's for reduction, yes. If the number is not like that, the number is just counted. Instead, the answer is A. How can it be A? 49 from where? That's just an example, I just give an example. If the question is like this, like that.

I use 53 4/4 - 1/4 53 4/4 - 1/4 how can it be 53 50 - 6 1/4 not 4 ah who works for a while many who are wrong maybe who works it is changed to a split mixture, right? then it gets

The part A, like that. Okay. I'll show you where your mistakes are. The one who worked 50 minus 25/4, then this 25/4 is changed into a split. So it's 50 minus 6/4. That's what you mean, right?

That's what you mean, right? This is the problem with this earlier, why did I answer A? Why? Okay, let's continue. Why are you wrong? Instead the answer becomes A. Because you only reduce 50 by 6. So 50 by 6 is 44. Then you immediately continue with 1 by 4. Not like that, friends. Remember.

This is negative 6 per 4. This is negative 6 per 4. Not positive. This is considered negative, friends. Remember yesterday's mixture? If negative 6 per 4, if it is poured, it becomes negative. Wait a minute.

If negative 6 is 1 per 4, if it is in the lebur, it becomes negative 6 minus 1 per 4. Not negative 6 plus 1 per 4. So if I lebur, this becomes...

50 minus 6 minus 1.4. That's it, friends. Okay, so 50 minus 6 is equal to 44 minus 1.4. Not plus 1.4. Okay, now 44 minus 1.4, I change it to 1.

You can use the second method, so 43 plus 4 divided by 4 is minus 1 divided by 4. This makes 43, 4 minus 1 is 3. So 43, 3 divided by 4. So the answer is the same, even though I work like this. Can you see the mistake? Okay.

Okay, so it's okay, the mistake is here, but for those who work with this method, it's okay, you just see it, oh, you understand the concept that this split can be changed into a split split, but the mistake is only in the mark, okay, good, good, good for friends, I almost forgot to explain

this case, you guys just because you asked me so I remember Oh yes I haven't explained it Okay let's continue, friends, let's go to number 11 please choose the answer, the polling appears on your cellphone, so just choose the answer, okay

60% choose section A. Okay, let's discuss it right away, guys. Number 11. Okay, number 11 is really easy. Let's just work it out. So, the multiple choice is the round number. So, we change what has to be changed. So, 100 plus 4 times 5.

multiplied by 25% is equal to 1/4, friends multiplied by 1/4 multiplied by 100 minus 20 multiplied by 5/2 Okay, we work 4 with 4 each divided by 4 this is one this is one, okay then

This is 20 with 2, each divided by 2. 2 divided by 2 is 1. 20 divided by 2 is 10. Okay. So, this is the same as 100 plus 1 per 5 multiplied by 100. Reduced. 10 multiplied by 5 is 50. So, reduced by 50. Okay. 1 per 5 multiplied by 100 is

each divided by 5, so 100 divided by 5 is equal to 20, okay? So 100 plus 20, 120, minus 50, so it's 70. So the answer is part A. Easy, right? The number 11, the wrong one, where is the wrong one? Because it's up to number 15, guys. One is not counted, the wrong one is there.

I'm not sure if I'm doing it right. I'm wrong at 25%. Okay. I forgot to multiply by 5. Okay. It's usually just a mistake. I'm not sure. Not because I don't understand. Where's 1? 10 divided by 1 is 10. Okay. Let's continue, guys. We don't need to discuss this for a long time because it's easy. Let's go to question number 12. Please choose the answer.

It's okay, it's wrong here. So when the test is correct. It's true, Yusuf. Number 12. Okay.

Only 45% of you choose C. What's the problem? Okay, guys. Some of you choose A, some of you choose C on YouTube. What's the problem? We have to discuss this well. So, guys, pay attention to this. The opposite is a mix of choices. Okay, let's change it all to a mix of choices. So, it's the same as...

3 plus 1/2, okay, times 12.5%. 12.5% is equal to 1/8, friends. I show you, this is a special fraction, but I show you how to get it. Well, yesterday I taught you to change the decimal percent to a fraction. So 12.5 we change it first to a fraction, this one first.

So, 125 per 10. Because one number is behind a comma. But because of percent, we add two zeros. So, 125 per 1000. Now, this can be simplified. Each is divided by 125. So, this is

125 divided by 125 is 1, 1000 divided by 125 is 8. So, the simple form of, the form of division of 12.5% is 1 per 8. This is in the table earlier, but I just show you how to process it so you don't get confused. But just remember, 12.5% is equal to 1 per 8. So, multiplied by 1 per 8, plus 3 per 2,

Divide this is 15 per 10, friends. Or you can use 3 per 2. Those who use 3 per 2 can also. We change this to times, then reverse it to 10 per 15. Minus 25%, that's equal to 1 per 4. Okay. Now we can draw the times. This is...

There is no one who can be corrected, so he only times the denominator with the denominator, the denominator with the denominator. This is 10 divided by 15, we can simplify it, each divided by 5, so this is 2, this is 3. Okay, then we can correct 2 divided by 2, 1, 3 divided by 3, 1. Okay, so the result is 1. Now, it turns out

3 plus 1 times 1, 1, 2 times 8, 16 plus, this is the result of 1, friends, minus 1 per 4. Now, this is later we operate the round number with the round number. 1 per 16 minus 1 per 4. Well, it's better if we directly change 1 per 4 to 1 per 16. The way is we multiply 4.

So that the name is the same, so that it doesn't take too long. So 1 times 4, 4, 4 times 4, 16. Okay, so 3 plus 1 is 4. 1 per 16 minus 4 per 16 is negative 3 per 16. 1 minus 4 is negative 3. Negative 3 per 16. So 4 minus 3 per 16.

Remember, this is reduced. If we reduce it with a smaller denominator, we use the second method. So, this is changed to 3 plus 1. One, we change it to 16 per 16. Then, it's reduced to 3 per 16. So, this is 3. 16 is reduced to 3. That's 13 per 16. So, the answer is part C.

Okay, not part B, but part C. This is the second way, I have explained it many times. So, God willing, you understand, friends. And what I want to ask, up to here, 4/16 follows the description, a split of the value. See the basic theory later. Where does 1 come from? It comes from here, 1 times 1, 1 times 1, 1 times 1, 1 divided by 1, yes 1. The fraction, it should be 5.

Which one is 5? I simplified it first, then I cut it out. That can also be done. Masuri, where did you come from? I explained 12.5 to be 1/8 here. 3 plus 16/16 from where? Okay. Just specifically for reduction. Yes, that's right. This is the way, specifically for reduction. 3/2 how?

3/2, this one is 10/15, I simplify it 10/15, I simplify it by dividing it by 5 each, so this is 2/3 okay 3/2 from this question, okay, don't follow the basic 2, you don't know why the answer is 4 - 3/16, because

3 plus 1 is 4, right? 1 minus 4 is negative 3, so here it is reduced. 12.5% minus 125 per 10. Yes, it's 125 per 10, but because there is a percentage, that's why we add the two zeros. If it's explained, listen, I've explained this negative 3 again, where is it from?

Okay, later watch Basic Tiu, watch Basic Tiu, that's the PR, all your questions are in Basic Tiu. Okay friends, let's continue to question number 13. Be excited, there are two more numbers, please choose the answer, friends.

This is who was on Zoom earlier, there are a few people, I can't imagine if I met you guys directly, fortunately it's only on the screen, I think I'm nervous if I see all of you guys directly. Okay, friends, hey, only 54% choose the part, okay, why, what's wrong, we have to get through this.

We have to get this right because only 52% chose the right answer. Okay, friends. How much is 150% of this? Okay, how much is 150%?

150% is 150 per 100. We simplify the zero line by 1. Okay. The rest is 15 per 10. 15 per 10, each of us divide 5. 15 divided by 5, 3. 10 divided by 5, 2. Okay, so 150% is 3 per 2. So it's the same as 3 per 2.

from that times, so from that times, we change everything to be a normal division, friends, 1 times 3, 3 plus 1, 4, so 4 times 3 plus 1 times 4 minus 1 times 6, now we equate the name KPK from 3, 4, and 6,

This is from Basic TU, the KPK is 12, friends. The addition of 3, 4, and 6 is 12. So we all change the name to 12.

This is followed by the sign here, plus here is also less. Now we just have to think, what is this for? So that it becomes 12, the name. 3 times what, so that it becomes 12? Dikali 4, which means this is also multiplied by 4. This is 4 multiplied by 3, which means this is also multiplied by 3. 6 multiplied by 2, which means this is also multiplied by 2. Okay, we just have to write the denominator, 4 multiplied by 4, 16.

1 times 3, 3. 1 times 2, 2. Okay, so this is 3 times 2 times 16 plus 3, 19. 19 minus 2 is 17 times 12. So we just have to draw again.

3 with 12, each divided by 3. 3 divided by 3, 1. 12 divided by 3, that's 4. 17 with 2 can't be divided, so we just have to multiply. 17 times 1, 17. 2 times 4, 8. So 17 divided by 8, there's none. We change it into a split, a mixture. The way is to use the division we did before. So 17 divided by 8,

2 times 8, 16, so 2 1 per 8, the answer is part D. Kak, where is 2 1 per 8? From changing the usual fraction to the fraction of the mixture, I have explained the method many times, but if you are good, you can not write it again like me. How? Anyone wants to be asked, please.

be patient, sis, yes, I'm patient from the beginning, my answer is right coach, but I'm still a little confused about the way it works, it's okay, if you understand it, it's amazing, so just practice, coach can be angry, not with the students, I'm at school, I'm always angry at the work

Because teaching math to you and the kids at school is very different, friends. You pay attention, right? So, even though you don't understand, but you pay attention, it's still good, it feels like that, friends. If the kids at school say, "Oh, I'm always right, but always not fast." It's okay, you're several steps ahead of the others, friends.

Okay, if we use 15 per 10, is it still the same result? It should be the same, because it's the same 15 per 10 with 3 per 2. Okay, let's continue, friends. Okay, one more number, friends. Everyone is excited. Who works tomorrow, who is still excited tomorrow, friends. It's not easy to be PNS, so we have to be excited.

please choose the answer you need a lot of questions like this to make it smoother, yes, it's true, later you will be given more, okay, it's still 54% who answered the part, okay, okay, let's just discuss it, friends, because it's already night, okay, this is your

So we write 8 minus, this can't be subtracted, so we just multiply negative 3 by negative 4, that's negative 12 per 7. Negative 6 divided by negative 7.

If there is negative 2 divided by negative 3, we can write it in the division as negative 2 per negative 3. But this negative is finished, so it's positive 2 per 3. So we can write this as 6 per 7. Okay, because negative 6...

per negative 7, negative divided by negative becomes positive. Okay, remember, negative divided by negative becomes positive. Now there is a change in the sign, negative with negative becomes plus. So 8 plus 12/7 plus 6/7.

This is the same name, so we just add it. 12 plus 6 is 18. So 8 plus 18 per 7. Now, 18 per 7 is a bigger denominator. So we can change it to a division. So 8 plus, using the division, you can divide it into the numbers. 2 times 7 is 14. So 2, 4 per 7.

7, 14, yes, right. So this is 8 plus 2, 10, 4 per 7. The answer is section D. Okay, friends, you can already know where the mistake is. The most wrong is marked again, right? At the end, why negative 3 is not multiplied by 7?

Why is it mentioned that if the round number is multiplied by the fraction, it cannot be sorted, it means we multiply it by the denominator. Okay, time is up. I immediately add 8 plus 12 plus 6. Hey, you can't do that, 8 is a round number, you can't immediately add it with the fraction, unless you want to make it a mixture.

Okay, you can, friends. Next, the last question. Please choose the answer. Okay, friends. 50% choose D. Okay, 50%. Only half. Okay, let's discuss, friends.

Okay, this is using decimal numbers, friends. The choice, yes. So what we have to do is change what can be changed. Coincidentally, here, everything is a round number and a fraction. So we work on the fraction. 5 minus negative 2 plus 3 per 4. Now, this is so that we can...

Operate the negative 2, we change it into a fraction. You can use the reduction method earlier, you can, friends. So 4 times 2 is negative 8 times 4 plus 3 times 4. Okay, this is multiplied. Okay, then multiplied by 2 times 3.

minus 0.6 minus 1.10 1.10 you can change it to decimal so 1.10 is 0.1 right? so this is equal to 5 minus negative 8 plus 3 is negative 5 so negative 5 per 4 times 2 per 3

minus 0.6 minus 0.1 is 0.5. So, we just need to operate this percal. 2 divided by 2 is 1, 4 divided by 2 is 2. Negative 5, this is per 6. Okay. Now, this is 0.5, we can... Wait, I'll show you. So, this is because...

What we find is negative negative, so this is 5 plus 5 divided by 6 minus 0.5. Remember 0.5 is the same as 1 divided by 2. So this is the feeling that we are better off if 0.5 is divided by 2. But we make both of them divided by 6 so that they can be operated. So we multiply both of them by 3.

Okay, so it's minus 1 times 3, 3 divided by 6. You can also change it into a fraction here, friends. If you change it into a fraction, it becomes 5 divided by 10. 5 divided by 10 is simplified, it becomes 1 divided by 2, it's the same. So, 5 plus 5 minus 3 is 2 divided by 6. 2 divided by 6 can be simplified, each divided by 2. 2 divided by 2 is 1, 6 divided by 2 is 3.

So 5 plus 1/3, sorry, 5 plus 1/3 or I can write 5 1/3. 5 1/3 is how much? Well, I've said it before, friends. 1/3 is equal to 33.33%, or if in decimal it is equal to 0.33.

So 5 divided by 3 is equal to 5.33. The answer is D. Okay. Tonight's class is quite long, guys. Four. Wow, amazing. It's true, 14 out of 5 questions. You're amazing. Tomorrow is not the coach Vira again who teaches. Yes, we rest first, calculate the calculation. Tomorrow TWK first. We refresh first with material that

Not counting first, later you will be more tense every day learning Tiu. So it's in turn, friends. "Kak, I'm right but it's different way." It's okay. I'm stressed, Coach. You must be stressed if you don't know basic Tiu. That's the key. So from the beginning I've said, you must be stressed if you don't follow basic Tiu, then immediately follow fast calculation. But fortunately,

in Bimbel Viracun we have a class recording, friends, so yesterday's class recording you can still watch it over and over again so there are many participants who even watch the basic tune until over and over again, then you can really understand it, friends, especially for those who

It's been a long time since I studied math, math, and you have to know yourself. If you guys really have to start, you really have to learn differently. It's the same as those who like math from school, you really study well from school, friends.

Finally, Coach Vira can teach me directly. Be patient. I hope you enter heaven. Amen. Amen, amen. So the most difficult thing to be a teacher is how to make people understand, friends. Understanding something.

Art to understand something with art to make people understand is different. And what a teacher needs, a teacher, is how art makes people understand. If we understand it ourselves, how can we pass it on to others is difficult. So that's why a lot of people in mathematics are genius people.

But he can't explain it to people, because those are two different arts, friends. Many of my friends who won the Olympics are international, national, but he can't explain to people what he understands. So I hope I can explain, convey to my friends, a good understanding, friends.

And once again, for those who don't follow Basic Tiu, watch Basic Tiu, all your questions are there. When will the book be released? I also wonder, when, friends? I hope I'm given more time to finish the book, friends. Watching a snake recording, where is the snake recording? On your account, on the website, on the application. Login, everything is there later.

Coach, coach, not teaching elementary school students who are already old, coach. But I'm more happy to teach CPNS fighters, friends. Honestly, I'm much happier to teach CPNS fighters than school children. Why? Because CPNS fighters have very high motivation. No matter how hard it is to understand, but the motivation is high. Because what you are fighting for is the future, work.

life until retirement, so the motivation is amazing, even though some are reluctant to understand, but God willing, with high motivation, slowly you will be able to, friends, don't be discouraged, don't be discouraged if you understand it will be long, because it really needs a process, the process of each person is different,

I have a Bimbel participant last year who followed all of my Bimbel, almost all of my Bimbel she followed. And from the beginning she understood it was really difficult, friends. Oh my God, but she was really excited, excited to work on everything. And finally she got a score of Tiu above 110 if I'm not mistaken.

So if he can start from only 60, the TO score becomes 100 or more, you can do it too. If you have the same spirit. If it's kafira, I understand it very quickly. Alhamdulillah.

Okay, friends, that's it for tonight, the class is quite long, I want to sleep after this, you guys also go to bed, don't be lazy, okay? Tomorrow I will work on PR and work on tasks. Thank you for your enthusiasm tonight, I'm sorry if there are any mistakes.

Honestly, all I said, all my reactions are just to be funny, friends. I want you to understand, hopefully no one is caught, accepted by misunderstanding. I'm sorry if anyone is offended or how, I'm sorry. Assalamualaikum warahmatullahi wabarakatuh. Bye bye.
