Answer 2

Resposta:

$d)\frac{2}{3} :\frac{4}{5} =\frac{2}{3} .\frac{5}{4} =\frac{1}{3} .\frac{5}{2} =\frac{5}{6}$

$e)\frac{3}{8} :1=\frac{3}{8} =0,375$

$f)\frac{4}{9} :\frac{1}{2} =\frac{4}{9} .2=\frac{8}{9}$

$g)\frac{2}{5} :\frac{5}{7} =\frac{2.7}{5.5} =\frac{14}{25}$

$h)\frac{1}{2} :\frac{11}{15} =\frac{1.15}{2.11} =\frac{15}{22}$

$i)\frac{2}{9} :\frac{3}{9} =\frac{2}{9} .\frac{9}{3} =2.\frac{1}{3} =\frac{2}{3}$

$j)\frac{8}{3} :4=\frac{8}{3} .\frac{1}{4} =\frac{2}{3}$

$k)\frac{4}{5} :8=\frac{4}{5} .\frac{1}{8} =\frac{1}{5} .\frac{1}{2} =\frac{1}{10}$

$l)\frac{9}{16} :\frac{3}{4} =\frac{9}{16} .\frac{4}{3} =\frac{3}{4}$
