Aptitude Question ID : 92809

Which of the following number is the greatest of all?
0.9, 0.\overline9, 0.0\overline9, 0.\overline{09}
[A]0.\overline{09}
[B]0.\overline9
[C]0.9
[D]0.0\overline9

\mathbf{0.\overline9}
0.9 = \frac{9}{10},
0.\bar9 = \frac{9}{9} = 1,
0.0\bar9 = \frac{9}{90} = \frac{1}{10},
0.\overline{09} = \frac{9}{99} = \frac{1}{11}
Hence option [B] is the right answer.
