Answer:
7/9 + (-7/9) = 0
Step-by-step explanation:
Definition of additive inverse:
Two numbers are additive inverses if their sum is zero.
For example, 2 and -2 are additive inverses since 2 + (-2) = 0.
Now your problem:
7/9 + (-7/9) =
7/9 and -7/9 are additive inverses.
Therefore, their sum is 0.
7/9 + (-7/9) = 0
