let x=0.010101. Now multiply x by 100 so the decimal moves two places to the right. So 100x=1.010101, if you notice theres a similarity of .010101 between each term which can be canceled out by subtraction

100x=1.010101 - x=0.010101 ---------------- 99x=1

Now just solve for x

Hope that all makes sense. You can always check this by calculating 1/99 to get .010101.
