# Additive Inverse of Rational Number:

(- 4)/7 + 4/7 = (- 4  +  4)/7 = 0.

Also, 4/7 + ((- 4)/7) = 0.

Similarly, (- 2)/3 + 2/3 = 0 = 2/3 + ((- 2)/3).

In the case of integers, we call – 2 as the additive inverse of 2 and 2 as the additive inverse of – 2.

For rational numbers also, we call (−4)/7 as the additive inverse of 4/7 "and" 4/7 as the additive inverse of (−4)/7.

Similarly, (−2)/3 "is the additive inverse of" 2/3 and 2/3 "is the additive inverse of" (−2)/3.

#### Example

What will be the additive inverse of (-3)/9?

(-3)/9 "as the additive inverse of" 3/9

#### Example

What will be the additive inverse of (- 9)/11?

(- 9)/11 "as the additive inverse of" 9/11.
