Question

find rational number lies between 3/7 and 2/3.

Answer 1

3/7 and 2/3
9/21 and 14/21 by taking lcm
so we can take 10/21 11/21 12/21 13/21 any you wish

Answer 2

$\huge \text {Solution}$


$let \: x \: = \frac{3}{7} \: and \: \frac{2}{3} . \: then \: \\ \\ a \: rational \: number \: lying \: between \: x \: and \: y \\ \\ = \frac{1}{2} (x + y) \\ = \\ \frac{1}{2} ( \frac{3}{7} + \frac{2}{3} ) \\ \\ = \frac{1}{2} ( \frac{9 + 14}{21} \\ \\ = \frac{1}{2} \times \frac{23}{21} \\ \\ = \frac{23}{42} \\ \\ hence \\ \frac{23}{42} \: is \: a \: rational \: number \: lying \: between \: \frac{2}{3} \: and \: \frac{3}{7}$
