Answer 2

[tex]We\ need\ to\ find\ the\ value\ of\ 0. \bar{9}\\ \\Let\ x=0. \bar{9}\\ or\ x = 0.999...\\multiply\ x\ by\ 10. We\ get\\10x = 10 \times 0.999...=9.999...\\ \\ Subtract\ x\ from\ 10x,\ we get\\10x-x=9.999...-0.999...\\ \Rightarrow 9x = 9\\ \Rightarrow x= \frac{9}{9} \\ \Rightarrow x = \boxed1\\\\ Thus, value\ of\ 0. \bar{9}\ is\ 1.
