# 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.
