If you want to know "why", you need to know how to solve it.
Write:
(Equation 1) x = 0.151515...
Multiply that by 100 (the factor 100, a one followed by two zeros, is chosen because the repetition occurs every two digits):
(Equation 2) 100 x = 15.151515...
Subtract equation 1 from equation 2, and solve the resulting equation for "x". That will give you the number as a fraction.
.015 as a fraction is 15/1000. In simplified form it is 3/200.
