KnowledgeBoat · Accepted Answer

(i) 9 Since, 9 + (-9) = 0 ∴ Additive inverse of 9 is -9. (ii) -11 Since, -11 + 11 = 0 ∴ Additive inverse of -11 is 11. (iii) For a rational number , the additive inverse is . + = 0 ∴ Additive inverse of is . (iv) First, express the number with a positive denominator: . Now, find the additive inverse: + = 0 ∴ Additive inverse of . (v) 0 Zero is its own additive inverse because 0 + 0 = 0. ∴ Additive inverse of 0 is 0.
