00:00Welcome everyone. So yes, a lot of people thought that the answer for this one is supposed to be 6 because this is 1's are. 3's are. So 3 multiplied by 3 is 9 minus 3. The answer is 6. No, that's not how these things work. Especially division. See, whenever there is a division involved with a fraction, you need to follow the rules of KCF, where K stands for keeping the first number as it is.
00:22C stands for changing the division sign to multiplication. F stands for flipping or taking the reciprocal of 3 by 4, which is 4 by 3 minus 3. This is 1's are. 4's are. So we are getting 4 multiplied by 4 minus 3. That is 16 minus 3. The answer for this question is supposed to be 13. I hope this is very very clear to everyone. That's it for today. I will see you in the next video.
