7.Find ten rational numbers between $$\frac { 3 }{ 5 }$$ and $$\frac { 3 }{ 4 }$$.
We have rational numbers as: $$\frac{3}5$$ and$$\frac{3}4$$
$$\frac{3}5=\frac{3×20}{5×20}=\frac{60}{100}$$ and $$\frac{3}4=\frac{3×25}{4×25}=\frac{75}{100}$$
So now we have to see ten rational number between $$\frac{60}{100}$$ and $$\frac{75}{100}$$
So, these can be, $$\frac{61}{100},\frac{62}{100},\frac{63}{100},\frac{64}{100},\frac{65}{100},\frac{66}{100},\frac{67}{100},\frac{68}{100},\frac{69}{100},\frac{70}{100}$$
