Detailed Answer:

Step 1: To convert 14.1930769 repeating into a fraction, begin writing this simple equation:

n = 14.1930769 (equation 1)

Step 2: Notice that there are 5 digits in the repeating block (30769) and 2 digits in the non-repeating part (19). Multiply both sides by 10⁷ = 10000000.

10000000 × n = 141930769.30769 (equation 2)

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

10000000 × n = 141930769.30769
     100 × n = 14.1930769
 9999900 × n = 141929350

1419293509999900 could be the answer, but it still can be put in the simplest form, i.e., reduced.

To simplify this fraction, divide the numerator and denominator by 50 (the GCF - greatest common factor).

n = 1419293509999900 = 141929350 ÷ 509999900 ÷ 50 = 2838587199998. So,
