Question

Simplifique as frações a seguir :
a)6/8
b)90/80
c)144/256
d)75/125
e)72/48​

Answer 1

Explicação passo-a-passo:

a)6/8

6/8 = 3/4

6 = 2 . 3 = 3

8 = 2 . 2 . 2 = 4

b)90/80

90/80 = 9/8

90 = 2 . 3 . 3 . 5 = 9

80 = 2 . 2 . 2 . 2 . 5 = 8

Pode-se também simplesmente, cancelar os zeros.

c)144/256

144/256 = 9/16

144 = 2 . 2 . 2 . 2 . 3 . 3 = 9

256 = 2 . 2 . 2 . 2 . 2 . 2 . 2 . 2 = 16

d)75/125

75/125 = 3/5

75 = 3 . 5 . 5 = 3

125 = 5 . 5 . 5 = 5

e)72/48

72/48 = 3/2

72 = 2 . 2 . 2 . 3 . 3 = 3

48 = 2 . 2 . 2 . 2 . 3 = 2
