11.2983 equals 559274950 as a fraction.

How do you turn 11.2983 repeating into a fraction?

Detailed Answer:

Step 1: To convert 11.2983 repeating into a fraction, begin writing this simple equation:

n = 11.2983 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (83) and 2 digits in the non-repeating part (29). Multiply both sides by 10⁴ = 10000.

10000 × n = 112983.83 (equation 2)

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

10000 × n = 112983.83
  100 × n = 11.2983
 9900 × n = 111854

1118549900 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 2 (the GCF - greatest common factor).

n = 1118549900 = 111854 ÷ 29900 ÷ 2 = 559274950. So,

11.2983 = 559274950 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 559274950 is also equal to 1114774950 when expressed as a mixed number.

The repeating decimal 11.2983 (vinculum notation) has a repeated block length of 2. It is also represented as 11.29838383... (ellipsis notation) which equals approximately 11.298383838383 (decimal approximation)(*).
