Question

a) (1/4) . (– 2/3) = c) (– 3/5) . (– 2/ 9) =
b) (– 5/3) . (4/7) = d) (1/8) . (3/7) =
c) (– 3/5) . (– 2/ 9) =
d) (1/8) . (3/7) =

Answer 1

Explicação passo-a-passo:

Na multiplicação de frações multiplicamos o dividendo com o outro dividendo e o divisor com o outro divisor.

a)(1/4).(-2/3)

-2/12=-1/6

b)(-5/3).(4/7)

-20/21

c)(-3/5).(-2/9)

6/45=2/15

d)(1/8).(3/7)

3/56
