Question

Write the additive inverse and multiplicative inverse of a rational number.

Answer 1

*The additive inverse of a number a is the number that, when added to a, yields zero.

Additive inverse of $a$ is $-a$.

*The reciprocal of a number obtained is such that when it is multiplied with the original number the value equals identity 1.

$a\times \frac{1}{a}=1$

$\frac{1}{a}$ is the multiplicative inverse of $a$ and $a$ is the multiplicative inverse of $a$.
