Question

Question 3(b) :

Replace $\square$ in each of the following by the correct number:

$\frac{5}{8}=\frac{10}{\square }$

Answer 1

The fractions given in the question are equal.

$\therefore$ 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. ($\because 10÷5=2$)

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

$\therefore$ We replace $\square$ by 16.
