This fractions worksheet is great for testing children in subtracting three fractions.
The problems may be selected for five different degrees of difficulty.

The easiest will keep the denominators the same and the numerators between 1 and 9.

The hardest will keep the numerators between 1 and 20 and the common denominators under 120.

The answer worksheet will show the progression on how to solve the problems.

First find the common denominator and adjust the fractions.

The next step is to add the numerators.

Then check to see if we need to simplify or reduce the fraction, and finally check to see if it is an improper fraction if it is we convert it to a mixed fraction.
