Question

What is the multiplicative inverse of c d ? Explain how a number is related to its multiplicative inverse.

Answer 1

Answer:

$\frac{d}{c}$

Step-by-step explanation:

If a be a real number,

Then the product of a and its multiplicative inverse is equal to the multiplicative identity, i.e. 1,

∵ $a\times \frac{1}{a}=1$

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

By comparing it,

We found that,

The multiplicative inverse of $\frac{c}{d}$ is $\frac{1}{c/d}$

i.e. $\frac{d}{c}$
