Prerequisites

Changing from a mixed number to improper form

1. Multiply the denominator by the integer (whole number).
2. Add the result to the numerator.
3. Place the answer in the numerator and keep the original denominator.

     = 5(1) +4 = 9 =

Changing from improper form to a mixed number

1. Divide the numerator by the denominator
2. Write down the integer (whole number) and next to it place the remainder in the numerator of a fraction.
3. Keep the original denominator.

   

5 goes into 9 one time with 4 leftover =
