Detailed Answer:

Step 1: To convert 0.11714285 repeating into a fraction, begin writing this simple equation:

n = 0.11714285 (equation 1)

Step 2: Notice that there are 6 digits in the repeating block (714285) and 2 digits in the non-repeating part (11). Multiply both sides by 10⁸ = 100000000.

100000000 × n = 11714285.714285 (equation 2)

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

100000000 × n = 11714285.714285
      100 × n = 0.11714285
 99999900 × n = 11714274

1171427499999900 could be the answer, but it still can be put in the simplest form, i.e., reduced.
