You are asking what is .12121212.... as a fraction.
Now the repeating part has length two. Let's call the decimal .12121212.... W ( for Wiki of course)
Now look at 100W=12.121212... Subtract W from 10W to get rid of the repeating part. 100W-W=12.12121212121....-.12121212121... so 99W=12 and W=12/99 which is 4/33 The answer I think you are looking for is:
4/33
Any double digit number over the same amount of 9s is equal to that number repeating
For example:
48/99 = 0.4848484848...
103/999 = 0.103103103103...
8/9 = 0.888888888888...
And therefore, 0.12121212... would have to be 12/99, which is simplified into 4/33
