Which of the following rational number lies between $$\frac{1}{4}$$​ and $$\frac{1}{2}$$​.

Correct option is C

Given:
We are to find a rational number that lies between$$\frac 14$$​ (0.25) and $$\frac 12$$​(0.5).
Solution:
Convert All Options to Decimals:
​$$\begin{align*}\frac{1}{8} &= 0.125 \quad (\text{less than } 0.25) \\\frac{3}{5} &= 0.6 \quad (\text{greater than } 0.5) \\\frac{3}{8} &= 0.375 \quad (\text{between } 0.25 \text{ and } 0.5) \\\frac{1}{6} &\approx 0.166 \quad (\text{less than } 0.25)\end{align*}$$​​
​$$\frac{3}{8} \text{ lies between } \frac{1}{4} \text{ and } \frac{1}{2}$$​​
