Question

2. Resolva as seguintes multiplicações e divisões de frações: a) 5 ⋅ 2 5 2 b) ÷ c) 49 ⋅ 25 ⋅ 6 4 d) 3 ÷ 3 7 3 7 15 14 35 3 e) 2 ÷ 6 f) 3 ÷ 1 g) 8 + 3 ⋅ h) 7 − 3 ⋅ 3 5 3 5

Answer 1

Resposta:

a) 5/3 x 2/7 = 10/21

b) 5/3 ÷ 2/7 = 5/3 x 7/2 =35/6

c) 49/15 x 25/14 x 6/35 = 7.350/7.350 ou 1 inteiro

d )3 ÷4/3 = 3 x 3/4 = 9/4

e) 2/3 ÷ 6 = 2/3 x 6 = 12/18

f) 3/5 ÷ 1/3 = 3/5 x 3/1 = 9/5

g) 8 + 3 x 1/5 = 11/55

h) 7-3x (5/6 - 2/3)=

7 - 3 x 3/3 = 4 x 3/3 = 12/3
