0.375

Explanation:


- 1 (7)/(8) + 2 (1)/(4) \\ = - (15)/(8) + (9)/(4) \\ = - (15)/(8) + (9 * 2)/(4 * 2) \\ = ( - 15 + 18)/(8) \\ = (3)/(8) \\ = 0.375

The answer to this would be 3/8.

you just simplify the given terms, so -1 7/8 can be simplified into -15/8 and 2 1/4 can be simplified into 9/4, add those together to get a sum of 3 over 8 or 3/8.

Good Luck
