Question

2) Efetue as divisões:
a) 5): (− 3\2)
b) (– 4): (− 3\5)
c) (– 5\2): (+ 2)
d) (– 3): (− 2\9)
e) (− 3\5): (+ 0,1)

Answer 1

Resposta:

a) 5 : ( − 3 / 2 ) =

5 × - 2 / 3 =

- 10 / 3 = - 3, 33

b) ( – 4 ) : ( − 3 / 5 ) =

- 4 × - 5 / 3 =

20 / 3 = 6, 66

c) ( – 5 / 2 ) : ( + 2 ) =

- 5 / 2 × 1 / 2 =

- 5 / 4 = - 1, 25

d) ( – 3 ) : ( − 2 / 9 ) =

- 3 × - 9 / 2 =

27 / 2 = 13, 5

e) ( − 3 / 5 ) : ( + 0,1 ) =

- 3 / 5 × 1 / 0, 1 =

- 3 / 0, 5 = - 6
