Answer:
3 1/4
Step-by-step explanation:
It's easiest to think of 3/4 + (-2 1/2) as (-2 1/2) + 3/4.
-2 1/2 represents the low end and 3/4 the high end. The sum is found by calculating the distance between them.
The distance from -2 1/2 to 0 is 2 1/2; that from 0 to 3/4 is 3/4.
So all we need to do now is to add up these two positive numbers:
2 2/4 + 3/4 = 2 5/4, or 3 1/4.
