Answer:
- 3/4
Step-by-step explanation:
-2 1/2 - (-1 3/4)
Subtracting a negative is like adding
-2 1/2 + (1 3/4)
Get a common denominator of 4
-2 2/4 + 1 3/4
The signs are different so we subtract and take the sign of the larger
2 2/4 - 1 3/4
Borrowing from the 2
1 4/4 + 2/4 - 1 3/4
1 6/4 - 1 3/4
3/4
2 2/4 was larger and it was negative so we add a negative sign
- 3/4
