Answer 1

Resposta:

A)

$\frac{4}{5}. \frac{2}{3} = \frac{8}{15}$

B)

$\frac{10}{3} \div \frac{5}{9} = \frac{10}{3} . \frac{9}{5} = \frac{90}{15} = 6$

C)

$\frac{6}{15} \div \frac{2}{3} = \frac{6}{15} . \frac{3}{2} = \frac{18}{30} = \frac{9}{15}$

D)

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

E)

$\frac{4}{5} \div \frac{2}{1} = \frac{4}{5} . \frac{1}{2} = \frac{4}{10} = \frac{2}{5}$

F)

$\frac{64}{27} \div \frac{128}{81} = \frac{64}{27} . \frac{81}{128} = \frac{5184}{3456}$

G)

$2 \times \frac{1}{4} \div 3 \times \frac{4}{7} = \frac{9}{4} . \frac{25}{7} = \frac{225}{28}$

H)

$\frac{6}{2} \div \frac{7}{1} = \frac{3}{1} . \frac{1}{7} = \frac{3}{7}$

i)

$\frac{13}{49} \div \frac{39}{14} = \frac{13}{49} . \frac{14}{39} = \frac{182}{1911}$

J)

$\frac{14}{3} \div 2 \times \frac{1}{3} = 4 \times \frac{2}{3} .2 \times \frac{1}{3} = \frac{14}{3} . \frac{7}{3} = \frac{98}{9}$
