Question

find three rational number between 1 by 5 and 1 by 4

Answer 1

$\frac{1}{5} \: and \: \frac{1}{4} \\ f \\ lcm \: of \: both \: the \: denominators = 20 \\ \frac{1}{5} \times \frac{4}{4} = \frac{4}{20} \\ \frac{1}{4} \times \frac{5}{5} = \frac{5}{20}$
$\frac{4}{20} \times \frac{5}{5} = \frac{20}{100} \\ \frac{5}{20} \times \frac{5}{5} = \frac{25}{100}$
The three rational no's are
$\frac{21}{100} . \frac{22}{100} . \frac{23}{100}$
