Question

Resolva as divisões de frações a) 3/5÷5/6 b) 7/6÷3/10 c) 2/3÷8/9 d) 2/5÷4/3

Answer 1

Resposta:

$a) \: \frac{3}{5} \div \frac{5}{6} \\ \\ \frac{3}{5} \times \frac{6}{5} \\ \\ \frac{18}{25}$

$b) \: \frac{7}{6} \div \frac{3}{10} \\ \\ \frac{7}{6} \times \frac{10}{3} \\ \\ \frac{70 \div 2}{18 \div 2} \\ \\ = \frac{35}{9}$

$c) \: \frac{2}{3} \div \frac{8}{9} \\ \\ \frac{2}{3} \times \frac{9}{8} \\ \\ \frac{18 \div6 }{24 \div 6} \\ \\ = \frac{3}{4}$

$d) \: \frac{2}{5} \div \frac{4}{3} \\ \\ \frac{2}{5} \times \frac{3}{4} \\ \\ \frac{6 \div 2}{20 \div 2} \\ \\ = \frac{3}{10}$
