Question

Given fraction $\frac{3}{8}\mathrm{and}\frac{9}{12}$are equivalent or not

Answer 1

We have, $\frac{3}{8}\mathrm{and}\frac{9}{12}$

To check the given fractions are equivalent or not, we take the cross product

$$\begin{gathered} 12\times 3\mathrm{and}9\times 8 \\ 36\mathrm{and}72 \end{gathered}$$

$\because$The cross product is not equal

Hence, $\frac{3}{8}\mathrm{and}\frac{9}{12}$ is not equivalent
