Question

The equivalent of $\frac{5}{7},$ whose numerator is $45$ is ________

Answer 1

The equivalent of $\frac{5}{7}=\frac{45}{Denominator},$

To get $45$ in the numerator multiply both numerator and denominator by $9$

$$\begin{gathered} \therefore \frac{5}{7}=\frac{(5\times 9)}{(7\times 9)} \\ =\frac{45}{63} \end{gathered}$$

So, the equivalent of $\frac{5}{7},$ whose numerator is $45$ is $\underline{\frac{\mathbf{45}}{\mathbf{63}}}$
