Question

Find ten rational numbers between $\frac{-2}{5}$ and $\frac{1}{2}$.

Answer 1

$\frac{-2}{5}$ and $\frac{1}{2}\to \frac{-2}{5}=\frac{-8}{20}$ and $\frac{1}{2}=\frac{10}{20}$

$\therefore$ Ten rational numbers are

$\frac{-7}{20},\frac{-6}{20},\frac{-5}{20},\frac{-4}{20},\frac{-3}{20},\frac{-2}{20},\frac{-1}{20},0,\frac{1}{20},\frac{2}{20}$

This question can have different multiple solutions too.
