Find
\left \begin{array}{rcl} 10 \times 0.\overline{9} &=& 9.\overline{9} \\ 1 \times 0.\overline{9} &=& 0.\overline{9} \end{array} \right\} - \\ \hline
(10−1)×0.¯9=9.¯9−0.¯99×0.¯9=99×0.¯9=9|:90.¯9=990.¯9=1
= 1 - 1 = 0
Note that........
(1.00000....) - (.9999......) = .(00000).....1 = .01 where the "bar" is over the "0'
{sorry.....I dont know how to insert the bar !!!}
0.ˉ3=133∗0.ˉ3=3∗13therefore0.ˉ9=11−0.ˉ9=1−1=0
