Question

Efetue as divisões:
a) 3/5 : 2/8 =
b) 5/6 : 2/3 =
c) 4/5 : 1/7 =
d) 3/7 : 2/5 =
e) 8/9 : 2/3 =

Answer 1

Resposta:

a) 3/5 : 2/8 =

5/3 • 2/8 = 10/28 simplifica por 2 = 5/14

b) 5/6 : 2/3 =

6/5 • 2/3 = 12/15 simplifica por 3 = 4/5

c) 4/5 : 1/7 =

5/4 • 1/7 = 5/28

d) 3/7 : 2/5 =

7/3 • 5/2= 35/6

e) 8/9 : 2/3 =

9/8 • 2/3 = 18/24 simplifica por 3 = 6/8
