How do you turn 14.4285 repeating into a fraction?

Detailed Answer:

Step 1: To convert 14.4285 repeating into a fraction, begin writing this simple equation:

n = 14.4285 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (285) and 1 digit in the non-repeating part (4). Multiply both sides by 10⁴ = 10000.

10000 × n = 144285.285 (equation 2)

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

10000 × n = 144285.285
   10 × n = 14.4285
 9990 × n = 144141

1441419990 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 3 (the GCF - greatest common factor).

n = 1441419990 = 144141 ÷ 39990 ÷ 3 = 480473330. So,

14.4285 = 480473330 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 480473330 is also equal to 1414273330 when expressed as a mixed number.

The repeating decimal 14.4285 (vinculum notation) has a repeated block length of 3. It is also represented as 14.4285285285... (ellipsis notation) which equals approximately 14.4285285285285285 (decimal approximation)(*).
