What is the sum of a rational number and its additive inverse?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The sum is always zero (0).
Formula: p/q + (-p/q) = 0
Examples:
- 3/7 + (-3/7) = 0
- -5/9 + 5/9 = 0
- 2/3 + (-2/3) = 0
Explanation: This is the defining property of additive inverse. The additive inverse is specifically the number that, when added to the original, gives zero.
