When dividing fractions, use the KCF rule: Keep the first fraction unchanged, Change division to multiplication, and Flip the second fraction. For example, 12 ÷ (8/4 ÷ 3×2) simplifies to 12 ÷ (2 ÷ 6) = 12 ÷ (1/3) = 12 × 3 = 36.

Added:Hello everyone.
Welcome to my channel.
In this exercise, you can see 12 divide on a fraction here.
8 divide on 4 in the numerator and 3 * 2 in the denominator.
But maybe it's best to write everything in a single line.
12 is here.
Divide on I have this fraction here. I can write it in a bracket.
>> [snorts] >> Numerator inside a parenthesis. 8 divide on 4 and this fraction line gets us a division sign.
And everything in the denominator is 3 * 2.
And I can close the parenthesis and everything inside the bracket, this bracket it stands for everything in this fraction line. So, now everything is much more easier to handle.
For examples with parenthesis or brackets, you should know you have to do parenthesis and brackets at first.
Inside this bracket, we have two parenthesis.
First, this parenthesis and then this parenthesis.
You know the answers of this parenthesis because 8 divide on 4 gives us 2.
And 3 * 2 gives us 6.
Okay, now I can write the result in another line.
12 is 12.
Divide on this bracket. And inside the bracket, you have two divide on six here.
Okay. Now, according to the rule I told you, first you have to do the bracket or parentheses. They are same.
But, inside the bracket, you have two divide on six.
It's not a clear number. You just can write it as uh first 12 divide on this answer. We don't know. Just write as a fraction two over six.
And now you can calculate this calculation, this expression very easily. But, you should know, in this case, you have two fractions divide on each other.
12 is also 12 over one. They are same.
As first fraction divide on the second fraction. In these cases, you have to respect the rules of KCF.
In KCF, K stands for keep unchanged the first fraction.
No changing, so 12 over one.
C stands for changing the operations from division to multiplication.
And at last, F stands for flipping the second fraction. Two over six gets six over two. Just flip the fraction here.
But, here, everything now gets very easy.
Because two over two is one.
Can be simplified with this 12.
Over two is six. And now, we have only 6 here * 6 here is 36. It's over 1 because the denominator are uh only 1. 1 * 1 is 1.
So, it's enough. 36. 36 is the last answer of this calculation.
Please like me here. Maybe you have any other suggestion or solution for this calculation.
