2 5

1.) Multiply the denominator by the whole number.

4 X 5 = 20

2.) Add the product (20) to the numerator. (2)

20 + 2 = 22

22 5

3.) The number you get in step 2 is your new numerator.

4.) The denominator stays the same.

Steps:

Converting from IMPROPER to MIXED.

1.) Divide the NUMERATOR (top number) by the DENOMINATOR (bottom number). Do NOT use a calculator.

2.) The answer will be a mixed number. The whole number is the QUOTIENT and the remainder becomes part of the fraction.

3.) The remainder becomes the NUMERATOR of the fraction and the DENOMINATOR is the DIVISOR.
