Hello!
First of all, since you're summing a negative number (-3/4), this is the same as subtracting it. So you get:
-4%2F5+-+3%2F4
Next, you need to find the Least Common Denominator (LCD) in order to make this sum. In this case, it's 20. Therefore, you get:


Therefore, the result is -31/20

I hope this helps!
