Question

1) Efetue as divisões indicadas, simplifique quando possível.

a)6÷2/5=
b)2/5÷3=
c)5/8÷7/2=
d)2/5÷3/2=
e)1/8÷1/2=
f)3 1/2÷7=
g)2÷ 15/2=
h)0÷31/9=

Answer 1

a) 6/1 • 5/2 = 30/2
30 ÷ 2 = 15
2 ÷ 2 = 1
15/1 ou 15

b) 2/5 • 1/3 = 2/15

c) 5/8 • 2/7 = 10/56
10 ÷ 2 = 5
56 ÷ 2 = 28
5/28

d) 2/5 • 2/3 = 4/15

e) 1/8 • 2/1 = 2/8
2 ÷ 2= 1
8 ÷ 2 = 4
1/4

f) 7/2 • 1/7 = 7/14
7 ÷ 7 = 1
14 ÷ 7 = 2
1/2

g) 2/1 • 2/15 = 4/15

h) 0 • 9/31 = 0
