Question

transformar em fração
h) 0,8883131...
i) 0,3210123123...
j)17,161515...

​

Answer 1

Comece sempre chamando a dízima de x:

h)

x = 0,8883131...

1000x = 888,3131

100000x = 88831,3131...

100000x - 1000x = 99000x = 87943

99000x = 87943

x = 87943/99000

g)

x = 0,3210123123...

10000x = 3210,123123...

10000000x = 3210123,123123...

10000000x - 10000x = 9990000x = 3206913

9990000x = 3206913

x = 3206913/9990000

i)

x = 17,161515...

100x = 1716,1515...

10000x = 171615,1515...

99000x = 169899

x = 169899/9900
