Solution

## The correct option is B (i) and (iii) The simplest way of representing a simple fraction is by eliminating the recurring decimal. This can be done by a multiplying factor which can be 10 or 100 or any other number depending on the number of recurring digits. x=0.¯¯¯¯¯¯18 ....(I) 100x=18.¯¯¯¯¯¯18 (multiplied by 100 because there are only two repeating digits) ….(II) Subtracting (I) from (II), 99x=18 Hence, the correct statements are (i) and (iii).
