Suppose you have a mixed fraction of the form ab/c where a, b and c are positive integers.

Multiply a * c = ac

Add b to this: ac + b

This is the numerator (top part) of your improper fraction.

The new denominator (bottom part) is the same as the old one, c

So the improper fraction = (ac+b)/c

Suppose the number was 34/5

3*5 = 15

15 + 4 = 19

The improper fraction is 19/5
