[00:00:01]Hello my friends. Today I have this example for you.

[00:00:05]20 divide on 15 divide on 10 divide on five.

[00:00:13]Only we have here division sign division operation. And you know when you have only one operation they are in same order for the calculation.

[00:00:25]It means when you are facing it this cases you have to start from the left side and then step by step goes to the right side.

[00:00:37]So, we only have a start only have to start from here 20 over 15.

[00:00:46]You can write only in a have a write it like a fraction.

[00:00:53]Then division sign 10 and the rest one here.

[00:01:00]But you know 10 is 10 over one and five is five over one.

[00:01:06]They all have a fraction form.

[00:01:10]And you know when you have fractions divide on each other you have to respect the rules for KCF.

[00:01:19]KCF means K stands for keep the first fraction because we are starting from these two fractions.

[00:01:30]This fraction divide on this fraction.

[00:01:33]K stands for keep unchanged the first fraction so I write it 20 over 15 unchanged.

[00:01:43]C stands for changing the division sign to the multiplication.

[00:01:50]Then F stands for flip the second fraction. It means inversion inversion of this fraction. 10 over 1 gives us 1 over 10.

[00:02:04]And for the second fraction, second pair of fractions, we only have or we only have to respect to this rule again.

[00:02:15]First fraction unchanged because now we have 1 over 10, okay? Then division to the multiplication.

[00:02:25]And the second fraction should be inverse or flipped.

[00:02:30]5 over 1 gives us 1 over 5. So, everything now is very simple.

[00:02:36]We only have to simplify them and multiply each other and we have the last answer.

[00:02:45]10 and 20 can be simplified.

[00:02:48]This one just gives us a one and this one gives us a two.

[00:02:55]Not other.

[00:02:57]We have a nothing for simplified, so for the numerator we have a two.

[00:03:05]And for the denominator we have a 15 * 5. Gives us 75.

[00:03:15]Yes, 75. 2 over 75 is the last answer of this calculation. Please write me here your way, your answers.
