In the picture, we can see that the decimal is repetitive. we can eliminate C because it is the only one that is non repetitive. 1/11 is 0.09090909…, which makes this fraction wrong. D is wrong because it equals to 0.083333…, which makes this fraction wrong. A is correct as 2/99 equals to 0.0202020202…, and since 02 is repetitive, this fraction is correct. Hope this helps.
