Question

Represente as dízimas na forma de fração geratriz.

Answer 1

a) x = 1,444...

x = 1 + 4/9

x = 13/9

b) x = 6,2828...

x = 6 + 28/99

x = 622/99

c) x = 0,942942

x = 942/999

d) x = 2,6999...

10x = 26,999...

10x = 26 + 9/9

10x = 243/9

90x = 243

x = 243/90

e) x = 3,241010...

100x = 324,1010...

100x = 324 + 10/99

100x = 32086/99

9900x = 32086

x = 32086/9900

f) x = 0,3888...

10x = 3,888...

10x = 3 + 8/9

10x = 35/9

90x = 35

x = 35/90
