PBJ · Answer 1

3 1/4 - 1 7/8

First, subtract the whole numbers (3 - 1 = 2):

= 2 1/4 - 7/8

Convert 1/4 to 2/8:

= 2 2/8 - 7/8

Borrow 1=8/8 from the 2:

= 1 10/8 - 7/8

Subtract 7/8 from 10/8:

= 1 3/8

The answer is 1 3/8

Alternatively, use improper fractions:

3 1/4 = 13/4 = 26/8

1 7/8 = 15/8

26/8 - 15/8 = 11/8 = 1 3/8
