Question

Additive inverse of -5/7
​

Answer 1

Step-by-step explanation:

In mathematics, the additive inverse of a number a is the number that, when added to a yields zero. This operation is also known as the opposite (number), sign change, and negation. ... For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0 .

Answer 2

Just change the symbol to opposite (plus)
Formula
a(-a) = 0
So Answer is +5/7
