Step 1: To convert 0.1114285 repeating into a fraction, begin writing this simple equation:

n = 0.1114285 (equation 1)

Step 2: Notice that there are 5 digits in the repeating block (14285) and 2 digits in the non-repeating part (11). Multiply both sides by 10⁷ = 10000000.

10000000 × n = 1114285.14285 (equation 2)

Step 3: Now subtract equation 1 from equation 2 to cancel the repeating block (or repetend) out.

10000000 × n = 1114285.14285
     100 × n = 0.1114285
 9999900 × n = 1114274

11142749999900 could be the answer, but it still can be put in the simplest form, i.e., reduced.
