Question

Encontre a geratriz da dízima periódica 0,2678888.. :

Answer 1

Resposta:

x = 0,267888... × 10

10x = 2,67888... × 10

100x = 26,7888... × 10

1000x 267,888.... × 10

10000x = 2678,88...

-----------------------------

10000x - 1000x = 2678,888... - 267,888...

9000x = 2411

$x = \dfrac{2411}{9000}$

Bons Estudos!
