Question

descubra as frações sequintes dizimas periódicas​

Answer 1

Resposta:

Explicação passo-a-passo:

a) 1,717171.... = 170/99

x = 1,717171...

100x = 171,7171...

100x = 171,7171...

- x = 1,7171...

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

99x = 170

x = 170/99

b) 8,513 513... = 5.505/999

x = 8,513 513...

1.000x = 8.513,513 513...

1.000x = 8.513,513 513...

- x = 8,513 513...

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

999x = 8.505

x = 8.505/999

c) 14,234 234... = 14.220/999

x = 14,234 234...

1.000x = 14.234,234 234...

1.000x = 14.234,234 234...

- x = 14,234 234...

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

999x = 14.220

x = 14.220/999
