Answer:

1  1/4

Step-by-step explanation:

3 1/8 - 1 7/8

I like to line them up vertically

3 1/8

- 1 7/8

---------------

We need to borrow from the 3

Take 1 from the 3 and make it 8/8

 2 (1/8+8/8)

- 1 (7/8)

---------------------

2 (9/8)

- 1 (7/8)

---------------------

1  2/8

Simplify the fraction by dividing by 2 on the top and bottom

1 1/4
