Answer:

-1/4

Explanation:

-3/4 - (-1/2)

-- = +

-(-1/2) = + 1/2

-3/4 + 1/2

The denominator of 1/2 needs to be the same as -3/4. What makes 1/2 have the same denominator as -3/4? Divide 4 by 2.

4/2 = 2

So, we must multiply both the top and bottom of one half by 2.

1 * 2 = 2

2 * 2 = 4

2/4

-3/4 + 2/4

Just add the top.

-3 + 2 = -1

-1/4
