Question

$\frac{6}{10} \times \frac{1}{3}$
$\frac{5}{7} \times \frac{3}{10}$
$36 \times \frac{5}{6}$
$\frac{4}{11} \times \frac{1}{2}$

​

Answer 1

Resposta:

$\frac{6}{10} \times \frac{1}{3} = \frac{6 \times 1}{10 \times 3} = \frac{6 \div 6}{30 \div 6} = \frac{1}{5} = 0.2 \\ \\ \frac{5}{7} \times \frac{3}{10} = \frac{5 \times 3}{7 \times 10} = \frac{15 \div 5}{70 \div 5} = \frac{3}{14} \\ \\ 36 \times \frac{5}{6} = \frac{36}{1} \times \frac{5}{6} = \frac{36 \times 5}{1 \times 6} = \frac{180}{6} = 30 \\ \\ \frac{4}{11} \times \frac{1}{2} = \frac{4 \times 1}{11 \times 2} = \frac{4 \div 2}{22 \div 2} = \frac{2}{11}$
