How do you turn 11.27461 repeating into a fraction?

Detailed Answer:

Step 1: To convert 11.27461 repeating into a fraction, begin writing this simple equation:

n = 11.27461 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (461) and 2 digits in the non-repeating part (27). Multiply both sides by 10⁵ = 100000.

100000 × n = 1127461.461 (equation 2)

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

100000 × n = 1127461.461
   100 × n = 11.27461
 99900 × n = 1126334

112633499900 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 = 112633499900 = 1126334 ÷ 299900 ÷ 2 = 56316749950. So,

11.27461 = 56316749950 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 56316749950 is also equal to 111371749950 when expressed as a mixed number.

The repeating decimal 11.27461 (vinculum notation) has a repeated block length of 3. It is also represented as 11.27461461461... (ellipsis notation) which equals approximately 11.27461461461461461 (decimal approximation)(*).
