How do you turn 10.26076 repeating into a fraction?

Detailed Answer:

Step 1: To convert 10.26076 repeating into a fraction, begin writing this simple equation:

n = 10.26076 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (076) and 2 digits in the non-repeating part (26). Multiply both sides by 10⁵ = 100000.

100000 × n = 1026076.076 (equation 2)

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

100000 × n = 1026076.076
   100 × n = 10.26076
 99900 × n = 1025050

102505099900 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 50 (the GCF - greatest common factor).

n = 102505099900 = 1025050 ÷ 5099900 ÷ 50 = 205011998. So,

10.26076 = 205011998 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 205011998 is also equal to 105211998 when expressed as a mixed number.

The repeating decimal 10.26076 (vinculum notation) has a repeated block length of 3. It is also represented as 10.26076076076... (ellipsis notation) which equals approximately 10.26076076076076076 (decimal approximation)(*).
