Question

Por favor me ajudem a resolver

Answer 1

Explicação passo-a-passo:

a) $\frac{2.(-6).(-3)}{9.(-2)}=\frac{36}{-18}=-2$

------------------------------------------------------------------------------

b) $\frac{6.(-2).(-3)}{-9}=\frac{36}{-9}=-4$

------------------------------------------------------------------------------

c) $\frac{6.(-4).(-5)}{3.(-8)}=\frac{120}{-24}=-5$

------------------------------------------------------------------------------

d) $\frac{(-2).(-3).(+4)}{2.3}=\frac{24}{6}=4$

------------------------------------------------------------------------------

e) $\frac{2.0.5}{30}=\frac{0}{30}=0$

-----------------------------------------------------------------------------

f) $\frac{-7.(-8)}{-14}=\frac{56}{-14}=-4$

-----------------------------------------------------------------------------

g) $\frac{-3-7-9}{19}=\frac{-19}{19}=-1$

-----------------------------------------------------------------------------

h) $\frac{(13-6+3)+5}{9-7+1}=\frac{15}{3}=5$

-----------------------------------------------------------------------------

i) $\frac{10.(-3)-40}{5.(-2)}=\frac{-30-40}{-10}=\frac{-70}{-10}=7$
