How do you turn 18.2383 repeating into a fraction?

Detailed Answer:

Step 1: To convert 18.2383 repeating into a fraction, begin writing this simple equation:

n = 18.2383 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (83) and 2 digits in the non-repeating part (23). Multiply both sides by 10⁴ = 10000.

10000 × n = 182383.83 (equation 2)

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

10000 × n = 182383.83
  100 × n = 18.2383
 9900 × n = 180560

1805609900 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 20 (the GCF - greatest common factor).

n = 1805609900 = 180560 ÷ 209900 ÷ 20 = 9028495. So,

18.2383 = 9028495 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 9028495 is also equal to 18118495 when expressed as a mixed number.

The repeating decimal 18.2383 (vinculum notation) has a repeated block length of 2. It is also represented as 18.23838383... (ellipsis notation) which equals approximately 18.238383838383 (decimal approximation)(*).

The recurring decimal 18.2383 can be written as a ratio of two integers having 9028 as the numerator and 495 as the denominator. So, it is a rational number (named after ratio). It can be shown that a number is rational if its decimal representation is repeating or terminating.
