Question

Question 3(a) :

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

$\frac{2}{7}=\frac{8}{\square }$

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 $\frac{2}{7}$, we multiply both the numerator and the denominator by 4. ($\because 8÷2=4$)

$\frac{2}{7}=\frac{2\times 4}{7\times 4}=\frac{8}{\begin{array}{c}28\end{array}}$

$\therefore$ We replace $\square$ by 28.
