$here \: is \: your \: answer \\ 3 \: rational \: number \: between \: \frac{2}{5} \: and \: \frac{1}{2} \: is \\ to \: find \: rationa \: number \: between \: them \: we \: will \: take \: the \: lcm \\ lcm \: of \: 5 \: and \: 2 \: is \: 10 \\ now \\ \frac{2 \: and \: 5}{10} \\ as \: there \: are \: not \: 3 \: rational \: between \: the \: given \: rational \: number \\ it \: will \: be \: mutiplied \: by \: 2 \\ \frac{2 \times 2}{10 \times 2} = \frac{4}{10} \: and \: \frac{5 \times 2}{10} = \frac{10}{10} \\ now \: the \: rational \: number \: are \: \\ \frac{5}{10} \: and \: \frac{6}{10} \: and \: \frac{7}{10} \: and \: \frac{8}{10}$
