Answer:
0, 0, 0
Explanation:
You want the sum of a number and its opposite for the numbers ...
3, 7.5, and -2 2/3
Additive inverse
The definition of the additive inverse (opposite) of a number is that it is the number that produces 0 when summed with the original number.
Any number summed with its opposite will give zero.
The sums are ...
- 3 + (-3) = 0
- 7.5 + (-7.5) = 0
- -2 2/3 + (2 2/3) = 0
