Question

Check whether the fraction are equivalent.

$\frac{4}{18},\frac{99}{162}$

Answer 1

To check whether the fraction are equivalent,

Consider $\frac{4}{18}$

On multiply both numerator and denominator by $9$, we have

$$\begin{gathered} =\frac{{\displaystyle 4\times 9}}{{\displaystyle 18\times 9}} \\ =\frac{36}{162}\ne \frac{99}{162} \end{gathered}$$

Hence, $\frac{4}{18}\ne \frac{99}{162}$

Hence, the fraction are not equivalent.
