Question
Find a rational number between $\frac{3}{8}$ and $\frac{2}{5}$
✓
Answer
$\frac{3}{8}$ and $\frac{2}{5}$ Let: $\text{x}=\frac{3}{8}$ and $\text{y}=\frac{2}{5}$
Rational number lying between $x$ and $y.$
$\frac{1}{2}(\text{x}+\text{y})=\frac{1}{2}\Big(\frac{3}{8}+\frac{2}{5}\Big)$
$=\frac{1}{2}\Big(\frac{15+16}{40}\Big)=\frac{31}{80}$
Rational number lying between $x$ and $y.$
$\frac{1}{2}(\text{x}+\text{y})=\frac{1}{2}\Big(\frac{3}{8}+\frac{2}{5}\Big)$
$=\frac{1}{2}\Big(\frac{15+16}{40}\Big)=\frac{31}{80}$
