Step 1: To convert 14.254615 repeating into a fraction, begin writing this simple equation:

n = 14.254615 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (4615) and 2 digits in the non-repeating part (25). Multiply both sides by 10⁶ = 1000000.

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

1000000 × n = 14254615.4615
    100 × n = 14.254615
 999900 × n = 14253190

14253190999900 could be the answer, but it still can be put in the simplest form, i.e., reduced.
