There are 3 simple steps to subtract fractions

1. Make sure the bottom numbers (the denominators) are the same.

2. Subtract the top numbers (the numerators). Put the answer over the same denominator.

3. Simplify the fraction (if needed).

1. 2 8/7 - 2 1/7 = ?

2 - 2 = 0

8 - 1 = 7

The fraction is 7/7. 7/7 is the same as 1.

0 + 1 = 1

2. 8 12/31 + 4 5/6 = 13.2204301075

13.2204301075 ≈ 13

3. 15 2/15 - 15 1/20

0.08333333333 ≈ 1
