Step 1: To convert 17.946153 repeating into a fraction, begin writing this simple equation:

n = 17.946153 (equation 1)

Step 2: Notice that there are 5 digits in the repeating block (46153) and 1 digit in the non-repeating part (9). 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 = 17946153.46153
     10 × n = 17.946153
 999990 × n = 17945974
