Answer : 1 7/8

Given that: 3 1/4 - 1 3/8

Step 1: Convert the mixed fraction into an improper fraction

3 1/4 = (4 x 3) + 1 / 4

3 1/4 = 12 + 1 / 4

3 1/4 = 13/4

1 3/8 = (8 x 1) + 3 / 8

1 3/8 = 8 + 3 / 8

1 3/8 = 11/8

13/4 - 11/8

The common denominator is 8

2 x 13 - 11 x 1 / 8

26 - 11 / 8

15/8

1 7/8

Therefore, the answer is 1 7/8
