Answer 2

Hey friend,
I think the question is 0.9 and bar on 9
Then,
Let 0.9bar be x
$x = 0.9999... \: \: \: \: \: (1)\\ \\ 10x = 9.9999... \: \: \: \: \: (2)\: \: \: \: (adding \: 10 \: to \: both \: sides) \\ \\ (subtracting \: (2) \: from \: (1) \: we \: get \\ \\ 10x - x = 9.9999... \: - 0.9999... \\ \\ 9x = 9 \\ \\ x = \frac{9}{9} \\ \\ x = 1$

Hope this helps!!!
