Question

Give four rational numbers equivalent to:
$\frac{-2}{7}$

Answer 1

We have,

$\begin{array}{c}\frac{-2}{7}\times \frac{2}{2}=\frac{-4}{14}\\ \frac{-2}{7}\times \frac{3}{3}=\frac{-6}{21}\\ \frac{-2}{7}\times \frac{4}{4}=\frac{-8}{28}\\ \frac{-2}{7}\times \frac{5}{5}=\frac{-10}{35}\end{array}$

Therefore,

$4$ equivalent rational numbers are $\frac{-4}{14},\frac{-6}{21},\frac{-8}{21},\frac{-10}{35}$
