How do you turn 11.10384 repeating into a fraction?

Detailed Answer:

Step 1: To convert 11.10384 repeating into a fraction, begin writing this simple equation:

n = 11.10384 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (384) and 2 digits in the non-repeating part (10). Multiply both sides by 10⁵ = 100000.

100000 × n = 1110384.384 (equation 2)

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

100000 × n = 1110384.384
   100 × n = 11.10384
 99900 × n = 1109274

110927499900 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 6 (the GCF - greatest common factor).

n = 110927499900 = 1109274 ÷ 699900 ÷ 6 = 18487916650. So,

11.10384 = 18487916650 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 18487916650 is also equal to 11172916650 when expressed as a mixed number.

The repeating decimal 11.10384 (vinculum notation) has a repeated block length of 3. It is also represented as 11.10384384384... (ellipsis notation) which equals approximately 11.10384384384384384 (decimal approximation)(*).
