Qual é a fração de
dizima periódica USAMOS (...)
3,123123123... ( veja REPETE ( 3 números) (1000)
x = 3,123123123...(1000) multiplica
1000x =3123,123123123...
1000x = 3123,123123123...
x = 3,123123123...SUBTRAI
---------------------------------------------------
999x = 3120,000000000...
999x = 3120
x = 3120/999
3,123123123... = 3120/999
ou PODEMOS simplificar
3,123123123...= 3120/999 ( divide AMBOS por 3)
3,123123123... = 1040/333
E a de 2,414141?
2,414141...( veja REPETE 2 números)(100)
x = 2,414141...(100(multiplica)
100x = 241,414141...
100x = 241,414141...
x = 2,414141...SUBTRAI
-------------------------------------------
99x = 239,000000...
99x = 239
x = 239/99
2,414141... = 239/99
