Question

What is the multiplicative inverse of y?

Answer 1

Answer:

The multiplicative inverse of y is $\frac{1}{y}$.

Step-by-step explanation:

Multiplicative inverse implies a value that you would multiply with the given value so as to give 1.

Let the multiplicative inverse of y be represented by a, so that;

a x y = 1

ay = 1

divide both sides by y to have,

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

Thus, the multiplicative inverse of y is $\frac{1}{y}$.

This is applicable to any given value. Examples:

i. Given 2, the multiplicative inverse is $\frac{1}{2}$.

⇒ 2 x $\frac{1}{2}$ = 1

ii. What is the multiplicative inverse of 5?

The required answer is $\frac{1}{5}$.
