The fractions given in the question are equal.

$∴$ They are equivalent.

To find an equivalent fraction of a given fraction, we may multiply both the numerator and the denominator of the given fraction by the same number.

For the given fraction $\frac{5}{8}$ , we multiply both the numerator and the denominator by 2. ( $∵ 10 \div 5 = 2$ )

$\frac{5}{8} = \frac{5 \times 2}{8 \times 2} = \frac{10}{\begin{matrix} 16 \end{matrix}}$

$∴$ We replace $□$ by 16.
