What is the multiplicative inverse of c/d? Explain how a number is related to its multiplicative inverse.
Lana71 [14]

Answer:

\frac{d}{c}

The multiplicative inverse of a number n is \frac{1}{n}

The product of the number and its multiplicative inverse = 1

n × \frac{1}{n} = 1

Thus the multiplicative inverse of \frac{c}{d} is

\frac{1}{\frac{c}{d} } = \frac{d}{c}
