If you would like to calculate 3 1/8 - 1 7/8 as a mixed number, you can do this using the following steps:

3 1/8 - 1 7/8 = 25/8 - 15/8 = (25 - 15) / 8 = 10/8 = 1 2/8 = 1 1/4

The correct result would be 1 2/8 which simplifies to 1 1/4.
In order to subtract 1 7/8 from 3 1/8 you must change 3 1/8 to 2 9/8. Now you can subtract 7/8 from 9/8 gives you 2/8. The whole numbers can be subtracted. 2 minus 1 is 1. So you now have 1 2/8 which can be simplified to 1 1/4.
