Detailed Answer:

Step 1: To convert 11.1607692 repeating into a fraction, begin writing this simple equation:

n = 11.1607692 (equation 1)

Step 2: Notice that there are 5 digits in the repeating block (07692) and 2 digits in the non-repeating part (16). Multiply both sides by 10⁷ = 10000000.

10000000 × n = 111607692.07692 (equation 2)

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

10000000 × n = 111607692.07692
     100 × n = 11.1607692
 9999900 × n = 111606576

1116065769999900 could be the answer, but it still can be put in the simplest form, i.e., reduced.
