d) 2:10/3=
e) 8,96:(-2,1)

Answer 1

Resposta:

Explicação passo a passo:

A) (11/9):(4/9)

= 11/9 . 9/4

= 9/9 . 11/4

= 11/4

b) (21/4):7

= 21/4 . 1/7

= 21/7 . 1/4

= 3.1/4

= 3/4

c) (-11/3):(-13/10)

= 11/3 . 10/13

= 110/39

d) 2:10/3

= 2 . 3/10

= 6/10 (:2)/(:2)

= 3/5

e) 8,96:(-2,1)

= - 8,96 : 2,10 . 100/100

= 896/210 (:4)/(:4)

= 224/55

= 4,2666

= 4,27
