Question

$1. \frac{2}{3} .\frac{12}{5} + \frac{3}{8} : \frac{3}{8} + \frac{1}{3} : \frac{4}{3} =$

Answer 1

Resposta:

$1 \times \frac{2}{3} \times \frac{12}{5} + \frac{3}{8} \div \frac{3}{8} + \frac{1}{3} \div \frac{4}{3} \\ \\ \frac{2}{3} \times \frac{12}{5} + 1 + \frac{1}{3} \times \frac{3}{4} \\ \\ 2 \times \frac{4}{5} + 1 + \frac{1}{3} \times \frac{3}{4} \\ \\ 2 \times \frac{4}{5} + 1 + \frac{1}{4} \\ \\ \frac{8}{5} + 1 + \frac{1}{4} \\ \\ \frac{32 + 20 + 5}{20} \\ \\ \frac{57}{20}$
