You need common denominators to solve this. So, what number do 2 and 4 share?
The number is "4"
1%2F2 + %28-3%2F4%29
1%2F2 = x%2F4
Since the "2" was multiplied by 2 to get 4, we do the same thing to the numerator, which is to multiply it by 2 as well.
1%2F2 = 2%2F4
Now, you can add the two fractions.
2%2F4 + %28-3%2F4%29
answer -1%2F4
