Detailed Answer:

Step 1: To convert 17.1146153 repeating into a fraction, begin writing this simple equation:

n = 17.1146153 (equation 1)

Step 2: Notice that there are 5 digits in the repeating block (46153) and 2 digits in the non-repeating part (11). Multiply both sides by 10⁷ = 10000000.

10000000 × n = 171146153.46153 (equation 2)

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

10000000 × n = 171146153.46153
     100 × n = 17.1146153
 9999900 × n = 171144442

1711444429999900 could be the answer, but it still can be put in the simplest form, i.e., reduced.
