Question

Find any two rational numbers $\frac{1}{4}$ and $\frac{3}{4}$.

Answer 1

A rational number between $\frac{1}{4}$ and $\frac{3}{4}=\frac{1}{2}(\frac{1}{4}+\frac{3}{4})=\frac{1}{2}\left(1\right)=\frac{1}{2}$
Another rational number between $\frac{1}{2}$ and $\frac{3}{4}=\frac{1}{2}(\frac{1}{2}+\frac{3}{4})=\frac{1}{2}\times \frac{5}{4}=\frac{5}{8}$
The rational numbers $\frac{1}{2}$ and $\frac{5}{8}$ lie between $\frac{1}{4}$ and $\frac{3}{4}$.
