MCQ
The additive identity of any rational number is _____.
- ✓$0$
- B$1$
- C$-1$
- D$2$
✓
Answer
Correct option: A.
$0$
The additive identity property says that if you add a real number to zero or add zero to a real number, then you get the same real number back.
The number zero is known as the identity element.
Then zero $(0)$ is the additive identity of a real number and all rational numbers are real.
Hence, $0$ is the additive identity of rational numbers.
