Answer 1

Resposta:

a) $-\frac{3}{14}$

b) $\frac{1}{27}$

c) $-1,458$

d) $4,68$

e) $-0,18$

Explicação passo-a-passo:

a) $(-2) . (-\frac{3}{4}).(-\frac{1}{7})= -2 . \frac{3}{4}.\frac{1}{7}=-\frac{3}{2}.\frac{1}{7}=-\frac{3}{14}$

b) $(-\frac{7}{9}).\frac{2}{7}.(-\frac{1}{6})=  \frac{7}{9}.\frac{2}{7} .\frac{1}{6} =\frac{1}{9} .2.\frac{1}{6}=\frac{1}{9}.\frac{1}{3}= \frac{1}{27}$

c) $(-1,5).(0,36).(2,7)=-(1,5.0,36.2,7) = (-0,54.2,7)=-1,458$

d) $(1,2).(6).(0,65)=7,2 . 0,65=4,68$

e) $(-0,8).(-0,45).(-0,5)=-(0,8.0,45.0,5)=-(0,36.0,5)=-0,18$
