Question

The additive universe of -7
19​

Answer 1

`(7)/(19)`.

Explanation:

Note: The number is not in proper form. Consider the given number is
`-(7)/(19)`.

If a number is added to another number and we get zero, then the added number is known as additive inverse.

Let a be a number, then

`a+(-a)=a-a=0`

So, -a is the additive inverse of a. It means, additive inverse is the same number with opposite sign.

Consider the given number is
`-(7)/(19)`.

`-(7)/(19)+(7)/(19)=0`

Therefore, the additive inverse of
`-(7)/(19)` is
`(7)/(19)`.
