How do you turn 19.623 repeating into a fraction?

Detailed Answer:

Step 1: To convert 19.623 repeating into a fraction, begin writing this simple equation:

n = 19.623 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (23) and 1 digit in the non-repeating part (6). Multiply both sides by 10³ = 1000.

1000 × n = 19623.23 (equation 2)

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

1000 × n = 19623.23
  10 × n = 19.623
 990 × n = 19427

n = 19427990 (answer)

19.623 = 19427990 as the lowest possible fraction.
