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
