Let X = -5.1212. ............. (1)
were, bar is on 12
since, Two digit are repeating,
Therefore we multiple both sides by 100.

$= > \: 100x = -512.121212.... .....(2)$

subtract (2) from (1) , we get

$= > \: \: 100x - x = (-512.1212....) - (-5.1212... )\\ = > 99x = 507 \\ \\ \: here \: \: x = \frac{507}{99}$
Answer is 507/99
