Question

(3/4+1/3x2/5) ÷ (4/3x5/2-3/4) qual o resultado desta expressão ?

Answer 1

$(\frac{3}{4} + \frac{1}{3} \times \frac{2}{5} ) \div (\frac{4}{3} \times \frac{5}{2} - \frac{3}{4} ) = \\ ( \frac{3}{4} + \frac{2}{15} ) \div ( \frac{20}{6} - \frac{3}{4} ) \\ ( \frac{15 \times 3 + 4 \times 2}{60} ) \div ( \frac{4 \times 20 - 6 \times 3}{24} ) \\ \frac{53}{60} \div \frac{62}{24} = \frac{53}{60} \times \frac{24}{62} = \\ \frac{53 \times 62 + 62 \times 60}{60 \times 62}$
