What is the multiplicative identity for rational numbers?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
The multiplicative identity is 1 (or 1/1).
Property: For any rational number p/q: (p/q) × 1 = p/q
Examples:
- 3/5 × 1 = 3/5
- -7/9 × 1 = -7/9
- 1 × 4/11 = 4/11
One is called the multiplicative identity because multiplying any number by 1 gives back the same number.
