Question

Which rational no. Is its own addititive inverse

Answer 1

Step-by-step explanation:

Let the rational number be "a"

according to the question,

the rational number is its own additive inverse.

=> additive inverse of a = a

We know,

sum of the number and its additive inverse = 0

a + a = 0

2a = 0

=> a = 0

The rational number which is additive inverse of itself is zero.
