Only 1 in 5 Can Solve This Math Challenge!

[00:00:00]Hello everyone.

[00:00:02]In this problem you have this fraction 5 / 3 everything / 5 * 3.

[00:00:12]The best way to solve this problem is to write everything in one single line. So, I put numerator and denominator separately in a parenthesis different parenthesis.

[00:00:26]5 / 3 as a numerator / because the division line is division sign.

[00:00:39]5 * 3 is the numerator and denominator.

[00:00:45]And now I can write and calculate everything separately really easily because we have two parenthesis, we can do calculate the parenthesis separately. 5 / 3 I can just write as a fraction.

[00:01:06]5 over 3 and / the result of these two these parenthesis which is 5 * 3 is 15.

[00:01:20]But you should know when you have two fractions 5 over 3 uh 3 and 15 over 1 is the another fraction.

[00:01:29]Divide on each other. In this case, you can respect the rule for KCF.

[00:01:38]KCF tells us K stands for keep on change the first fraction. First fraction is 5 over 3. So, 5 over 3.

[00:01:52]C stands for changing the division sign to multiplication.

[00:01:58]So, I change it.

[00:01:59]And F stands for flipping the second fraction.

[00:02:05]15 over 1 gives us 1 over 15. We flipped it.

[00:02:12]And now you can see five can be cancelled and can be simplified with this 15.

[00:02:20]Five is 1 over 5 and 15 over 5 is 3.

[00:02:27]So, numerator is 1 * 1 and denominator is 3 * 3 gives us 9.

[00:02:38]1 over 9 is the last answer of this calculation.
