Question

find the rational numbers between-2/5,and1/5​

Answer 1

First rational no

$\frac{1}{2} \times ( \frac{ - 2}{5} + \frac{1}{5} )$

$= > \frac{1}{2} \times \frac{ - 2 + 1}{5}$

$= > \frac{1}{2} \times - \frac{1}{5}$

$= > \frac{ - 1}{10}$

Second rational no

$\frac{1}{2} \times ( - \frac{1}{10} + \frac{( - 2)}{5} )$

$= > \frac{1}{2} \times ( \frac{ - 1}{10} + \frac{ - 4}{10} )$

$= > \frac{1}{2} \times \frac{ - 5}{10}$

$= > \frac{ - 5}{20}$

Third rational no

$\frac{1}{2} \times ( \frac{ - 1}{10} + \frac{1}{5} )$

$= > \frac{1}{2} \times \frac{ - 1 + 2}{10}$

$= > \frac{1}{2} \times \frac{1}{10}$

$= > \frac{1}{20}$

Forth rational no

$\frac{1}{2} \times ( \frac{ - 1}{10} + \frac{1}{20} )$

$= > \frac{1}{2} \times \frac{ - 2 + 1}{20}$

$= > \frac{1}{2} \times \frac{ - 1}{20}$

$= > \frac{ - 1}{40}$
