$\huge\color{hotpink}\boxed{\colorbox{black}{Answer}}$

Given:-

$- \frac{2}{5} \: \: and \: \: \frac{1}{2}$

To Assume:-

• Rational no. between

Solution:-

$→ - \frac{2}{5} \: \: and \: \: \frac{1}{2} \\ \\ →lcm = 10 \\→ - \frac{2}{5} \times 2 \: \: and \: \: \frac{1}{2} \times 5 \\→ - \frac{4}{10} \: \: and \: \: \frac{5}{10}$

$\infty Integer \: \: answer = - \frac{3}{10}, - \frac{2}{10} \: and \: - \frac{1}{10}$

$Positive \: answer = \frac{1}{10} ,\frac{2}{10} \: and \: \frac{3}{10}$
