Question

me ajudem por favor eu do 70 pontos!!!!!​

Answer 1

1⁰) a) x = 0,525252...

100x = 52,5252...

100x = 52 + x

100x - x = 52

99x = 52

x = 52/99

B) x = 0,666...

10x = 6,66...

10x = 6 + x

10x - x = 6

9x = 6

x = 6/9

x = 2/3

C) x = 0,32444...

100x = 32,444...

100x = 32 + 4/9

100x = 292/9

900x = 292

x = 292/900

x = 73/225

D) x = 5,24124124...

100x = 524,124124...

100x = 524 + 124/999

100x = 523600/999

99900x = 523600

x = 523600/99900

x = 5236/999
