Answer 1

$( frac{9}{24}+frac{2}{24}+frac{20}{24} ):(frac{2}{24}+frac{8}{24}+frac{20}{24})= frac{31}{24}: frac{30}{24} = frac{31}{24}* frac{24}{30}= frac{31}{30}$

$( frac{24}{36}-frac{6}{36}-frac{16}{36} ):(frac{28}{36}-frac{15}{36}-frac{10}{36})= frac{2}{36}: frac{3}{36}= frac{2}{3}$

$( frac{9}{4}*frac{4}{3}*frac{8}{9} ):(frac{6}{5}*frac{4}{9}*frac{5}{2})=2$
