What is the additive identity for rational numbers?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The additive identity for rational numbers is 0 (or 0/1).
Property: For any rational number p/q: p/q + 0 = p/q
Examples:
- 3/4 + 0 = 3/4
- -5/7 + 0 = -5/7
- 0 + 2/3 = 2/3
Zero is called the additive identity because adding it to any number gives back the same number.
