C)2/9:11/3
D)1/2:4
E)10:2/5
F)3/8:5

Answer 1

Resposta:

$a) \: 4 \div \frac{1}{2} \\ \\ \frac{4}{1} \times \frac{2}{1} \\ \\ = 8$

$b) \: 60 \div \frac{11}{3} \\ \\ \frac{60}{1} \times \frac{3}{11} \\ \\ \frac{180}{11}$

$c) \: \frac{2}{9} \div \frac{11}{3} \\ \\ \frac{2}{9} \times \frac{3}{11} \\ \\ \frac{6 \div 3}{99 \div 3} \\ \\ = \frac{2}{33}$

$d) \: \frac{1}{2} \div 4 \\ \\ \frac{1}{2} \times \frac{1}{4} \\ \\ \frac{1}{8}$

$e) \: 10 \div \frac{2}{5} \\ \\ \frac{10}{1} \times \frac{5}{2} \\ \\ \frac{50}{2} \\ \\ = 25$

$f) \: \frac{3}{8} \div 5 \\ \\ \frac{3}{8} \times \frac{1}{5} \\ \\ \frac{3}{40}$
