Question

What is 2/4 +(-8/4) i'm a little stuck

Answer 1

the answer should be
2/4 +(-8/4)= -1.5

Answer 2

Well adding a negative to a positive is basically subtraction. 2/4+-8/4 would be -6/4. 
This is because 2 isn’t enough to get rid of -8, so we end up with -6.

Oh and -6/4 can be simplified to -3/2.
