Detailed Answer:

Step 1: To convert 1.4076923 repeating into a fraction, begin writing this simple equation:

n = 1.4076923 (equation 1)

Step 2: Notice that there are 6 digits in the repeating block (076923) and 1 digit in the non-repeating part (4). Multiply both sides by 10⁷ = 10000000.

10000000 × n = 14076923.076923 (equation 2)

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

10000000 × n = 14076923.076923
      10 × n = 1.4076923
 9999990 × n = 14076909
