How do you turn 12.483 repeating into a fraction?

Detailed Answer:

Step 1: To convert 12.483 repeating into a fraction, begin writing this simple equation:

n = 12.483 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (83) and 1 digit in the non-repeating part (4). Multiply both sides by 10³ = 1000.

1000 × n = 12483.83 (equation 2)

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

1000 × n = 12483.83
  10 × n = 12.483
 990 × n = 12359

n = 12359990 (answer)

12.483 = 12359990 as the lowest possible fraction.

As the numerator is greater than the denominator, we have an improper fraction, so we can also express it as a mixed number, thus 12359990 is also equal to 12479990 when expressed as a mixed number.
