Subtracting Fractions Subtracting mixed numbers is just like subtracting fractions, except that you have to subtract the whole numbers as well as the fractions.

Rename You borrow from the whole number four. 1 = 3 8 + 1 = 3 9 1 = 3 8 + 1 = 3 9 8 8 8 8

Subtract the fractions and the whole numbers. 3 9 - 1 5 = 2 4 8 8 8 Step 2 Subtract the fractions and the whole numbers. 3 9 - 1 5 = 2 4 8 8 8
