Question

which is rational number has additive inverse but not multiplicative inverse.​

Answer 1

Answer:

Negative or Additive inverse: - or minus is the additive inverse for Rational, natural, whole numbers and integers, since adding its additive inverse to a number results in zero. Hence, a + (-a) = (-a) + a = 0, where a can be rational number or natural number or whole number of integer.

Answer 2

Answer:

0 ( zero) is the only Rational nimber, which is its own additive inverse.

Additive inverse of ….

2 is -2

-3 is 3

7/9 is -7/9

-1 is 1

1 is -1

I gave above few examples , each is additive inverse of the other because their sum = 0. For finding additive inverse we only need to change its sign.

& if we need both numbers equal , it has to be 0. Since 0+0 = 0
