Answer 1

a) (-0,5)×1/2 = -1/4

b ) 2×(-1/9)= -2/9

c ) (-2/5)×(-3/7)= 6/35

d) (3/7)×(-1/2)=-3/14

e ) (-1/3)×2×(-3)=6/3=2

f) (-2)×(-1/2+5/3) =(-2)×(7/6)=-14/6

Answer 2

Resposta:

Explicação passo-a-passo:

A) (-0,5)×1/2

= - 5/10 . 1/2

= -5/20 (:5)/(:5)

= -1/4

B) 2× (-1/9)

= -2/9

C)(-2/5)×(-3/7)

= 6/35

D) (+3/7) × (-1/2)

= -3/14

E)(-1/3)×2× (-3)

= -1/3 . (-6)

= 6/3

= 2

F) (-2)×(-1/2 + 5/3)

= (-2) . [3.(-1) + 2.5]/6

= - 2. [-3+10]/6

= - 2. 7/6

= -14/6 (:2)/(:2)

= -7/3
