Question

Find the multiplicative inverse of $3$ ?

Answer 1

Multiplicative inverse:

The multiplicative inverse of a number is defined as when a number is multiplied by its original number, it gives the product as $1$.

Let us consider the number $a$ then the multiplicative inverse of the number is $\frac{1}{a}$.

According to the question,

The given value is $3$

a number is multiplied by a given number, it gives the product as $1$. (i,e. Multiplicative inverse is reciprocal of the given number)

$3\times \overline{)\frac{1}{3}}=1$

Therefore, the multiplicative inverse of $3$ is $\frac{1}{3}$.
