Question

Multiply and match the correct answer.

• A. $\frac{3}{4}$
• B. $31$
• C. $72$
• D. $132$

Answer 1

We know that, if a rational number is multipled by an integer, the numerator of the rational number gets multiplied by the integer and denominator will not be changed.

$\frac{9}{2}\times 16=\frac{144}{2}=72$

$88\times \frac{3}{2}=\frac{264}{2}=132$

When we multiply two rational numbers, then the numerator gets multiplied and the denominator gets multiplied.

$\frac{9}{2}\times \frac{1}{6}=\frac{9}{12}=\frac{3}{4}$

$\frac{14}{6}\times \frac{93}{7}=\frac{1302}{42}=31$
