#### Explanation:

Because you use KFC... Keep Flip Change.

Simplified makes

A fraction is actually a division problem so to divide two fractions set it up as a division problem or complex fraction. This makes the most sense.

Now multiply both the top fraction and the bottom fraction by the inverse of the bottom fraction. This makes sense because multiply by

Also multiplying by the inverse equals one

Dividing a fraction by a fraction makes sense and is easier to remember, even thought it takes longer.

The fraction

Quarters are obtained when a whole number is divided into four equal pieces, each is a quarter.

To find the number of quarters there are, multiply a number by

In

However, when dividing by

(or how many times can

That means, once you have the total number of quarters, divide them into groups of three's - each group will be 'Three' quarters.

You do this by dividing the total number of quarters by

In

Hence

(ie. once with a bit left over.)

Hence

In

.

In each case we are multiplying by

Hence the simple rule of Multiply and flip.
