Answer 1

$\frac{ \sqrt{5} }{ \sqrt{7} } = \sqrt{ \frac{5}{7} } . \\ \frac{ \sqrt{3} }{ \sqrt{11} } = \sqrt{ \frac{3}{11} } . \\ \frac{ \sqrt{8} }{ \sqrt{10} } = \sqrt{ \frac{8}{10} } = \sqrt{ \frac{4}{5} } . \\ \frac{ \sqrt{9} }{ \sqrt{81} } = \sqrt{ \frac{9}{81} } = \sqrt{ \frac{1}{9} } (= \frac{1}{3} ).$
