Answer:
1/4, or 0.25
Explanation:
so -1/2 can be rewritten as -2/4 since you multiply by 2/2, which is 1, so the value stays the same. Now that the denominators in both -2/4 and 3/4 are the same (it's 4), you add the values on top of the fractions. -2 plus 3 is 1. Your final answer is 1 over 4, so 1/4
Another way would be to convert to decimals. -1/3 is -0.5, 3/4 is 0.75, subtract 0.5 from 0.75 and you get 0.25, which is 1/4
