Answer 1

Resposta:

$a) \frac{3}{10} \times 5 = \frac{15}{10} = \frac{3}{2}$

$c) \frac{6}{12} \times \frac{3}{11} = \frac{18}{132} = \frac{9}{66} = \frac{3}{22}$

$e)6 \times \frac{2}{3} = \frac{12}{3} = 4$

$g) \frac{3}{8} \times \frac{4}{8} \times \frac{5}{3} = \frac{60}{192} = \frac{30}{96} = \frac{15}{48 } = \frac{5}{16}$
