Detailed Answer:

Step 1: To convert 2.32076923 repeating into a fraction, begin writing this simple equation:

n = 2.32076923 (equation 1)

Step 2: Notice that there are 6 digits in the repeating block (076923) and 2 digits in the non-repeating part (32). Multiply both sides by 10⁸ = 100000000.

100000000 × n = 232076923.076923 (equation 2)

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

100000000 × n = 232076923.076923
      100 × n = 2.32076923
 99999900 × n = 232076691
