Answer:

$\frac{10}{7}$

Step-by-step explanation:

$let \: the \: rational \: number \: be \: x \\ now \\ = \frac{1}{5} \: of \: x \: = \frac{2}{7} \\ = \frac{1}{5} \times x = \frac{2}{7} \\ = \frac{x}{5} = \frac{2}{7} \: \\ now \: on \: cross \: multiplying \: \\ = 7 \times x = 5 \times 2 \\ = 7x = 10 \\ = x = \frac{10}{7}$

$hence \: the \: rational \: number \: is \: \frac{10}{7}$
