\text { Find ten rational numbers between } \frac{3}{5} \text { and } \frac{3}{4}
Let us make the denominators same, say 80.
\begin{array}{l} \frac{3}{5} \Rightarrow \frac{3 \times 16}{5 \times 16}=\frac{48}{80} \\ \frac{3}{4} \Rightarrow \frac{3 \times 20}{4 \times 20}=\frac{60}{80} \end{array}
\begin{aligned} &\text { Ten rational numbers between } \frac{3}{5} \text { and } \frac{3}{4}=\text { ten rational numbers between } \frac{48}{80} \text { and } \frac{60}{80}\\ &\therefore \text { ten rational numbers between } \frac{48}{80} \text { and } \frac{60}{80}=\frac{49}{80}, \frac{50}{80}, \frac{51}{80}, \frac{52}{80}, \frac{54}{80}, \frac{55}{80}, \frac{56}{80}, \frac{57}{80}, \frac{58}{80}, \frac{59}{80} \end{aligned}
