Answer»

$let \;<klux>X</klux> = 2.2\<klux>BAR</klux>{18} \\ \\ Multiply \: \; by \: \: <klux>10</klux>\;\; on \;\;both \; \; sides\\ \\ \\\\10x = 22.\bar{18} \\ \\ \\ \mathbf{ as \;\;there \;\;are \;\;2 \;\;numbers\;\; under\;\; bar, \;\; multiply\;\; by \;\;100 }\\1000x = 2218.\bar{18}$

SUBTRACT 10 x from both sides,

990x = 2196

x = 2196/990

2.218 ( bar) = 2196/990
