Resposta:

A)3/4÷5/7=

$\frac{3}{4} \div \frac{5}{7} = \frac{3}{4} \times \frac{7}{5} = \frac{21}{20}$

B)2/3÷4/5=

$\frac{2}{3} \div \frac{4}{5} = \frac{2}{3} \times \frac{5}{4} = \frac{10}{12} = \frac{5}{6}$

C)4/9÷1/2=

$\frac{4}{9} \div \frac{1}{2} = \frac{4}{9} \times \frac{2}{1} = \frac{8}{9}$

D)2/5÷5/7=

$\frac{2}{5} \div \frac{5}{7} = \frac{2}{5} \times \frac{7}{5} = \frac{14}{25}$

E)1/2÷11/15=

$\frac{1}{6} \div \frac{11}{15} = \frac{1}{6} \times \frac{15}{11} = \frac{15}{66} = \frac{5}{33}$

F)2/9÷3/9=

$\frac{2}{9} \div \frac{3}{9} = \frac{2}{9} \times \frac{9}{3} = \frac{18}{27} = \frac{2}{3}$

G)9/16÷3/4=

$\frac{9}{16} \div \frac{3}{4} = \frac{9}{16} \times \frac{4}{3} = \frac{36}{48} = \frac{3}{4}$

H)8/5÷1/3=

$\frac{8}{5} \div \frac{1}{3} = \frac{8}{5} \times \frac{3}{1} = \frac{24}{5}$
