Answer:
-1.25 or -10/8
Explanation:
the additive inverse of a number is the number that would make it zero when added
ex. the inverse of 5 is -5 because 5+(-5)=0
so the inverse of -5/8 is 5/8 because -5/8+5/8=0. The question said to subtract the additive inverse.
-5/8-(5/8)=
-5/8-5/8=
-10/8 or -1.25
