Question

pfv me ajudem e pra hoje ​

Answer 1

Resposta:

A)

$\frac{4}{7} \times ( \frac{ - 3}{16} ) = \\ \: \ \frac{ - 12}{112} = \\ \frac{ - 3}{6} = \\ \frac{ - 1}{2}$

B)

$\frac{3}{4} \times \frac{4}{5} \times ( \frac{ - 5}{7} ) = \\ \frac{ - 60}{140} = \\ \frac{ - 6}{14} = \\ \frac{ - 3}{7}$

C)

$\frac{7}{3} \times \frac{6}{2} \times ( - 0.5) = \\ \frac{42}{6} \times ( - \frac{1}{2} ) = \\ 7 \times ( \frac{ - 1}{2} ) = \\ \frac{ - 7}{2}$

Ps : Sempre lembre de simplificar as frações!
