Question

Give four rational numbers equivalent to:

$\frac{-2}{7}$

Answer 1

Given $\frac{-2}{7}$
$\frac{-2\times 2}{7\times 2}=\frac{-4}{14},\frac{-2\times 3}{7\times 3}=\frac{-6}{21},\frac{-2\times 4}{7\times 4}=\frac{-8}{28},\frac{-2\times 5}{7\times 5}=\frac{-10}{35}$
Therefore, four equivalent rational numbers are $\frac{-4}{14},\frac{-6}{21},\frac{-8}{28},\frac{-10}{35}$
