00:00Welcome everyone. So today we are going to understand why the answer for this question is not supposed to be 1.
00:06See this is cancelling, right? So 77 divided by 77, the answer is 1.
00:11No, that's not how these things work. Please understand in division and multiplication,
00:17whenever you have sums like these, you have to remember that they hold equal precedence.
00:21So you need to go from left to right. Whatever operation happens first on your left hand side has to be done first.
00:26So first we will do 77 divided by 77 upon 7.
00:32Now whenever you have a division, a fraction involved in division, we will have to follow the rules of KCF.
00:38Where K stands for keeping the first number as it is.
00:42C stands for changing the division sign to multiplication.
00:46F stands for flipping or taking reciprocal of 77 upon 7, which is 7 upon 77 multiplied by 7.
00:54So this is cancelling and then you are left with 7 multiplied by 7.
00:59Answer for this question is supposed to be 49.
01:02I hope this is very very clear to everyone.
