1/2 + (-3/4)= <br> i need help /:
Marysya12 [62]

Start by converting to like terms, so convert 1/2 to 2/4.

Next, look at the problem. You are adding a negative, which is the same as subtracting, so your new problem looks like this: 2/4 - 3/4.

If you take 3/4 from 2/4, you are left with -1/4. This is your final answer!
