Question

Name the property indicated in the following:
$\frac{8}{9}\times 1=\frac{8}{9}$

Answer 1

We know that for the set of rational numbers, $1$ is said to be multiplicative identity. It means when any rational number is multiplied to $1$ or $1$ is multiplied to any rational number, the result is that rational number itself.

Here, a rational number $\frac{8}{9}$ is multiplied to $1$, the result is that rational number itself that is $\frac{8}{9}$.

Hence, $1$ is the multiplicative identity in the given expression $\frac{8}{9}\times 1=\frac{8}{9}$.
