How do you turn 11.192307 repeating into a fraction?

Detailed Answer:

Step 1: To convert 11.192307 repeating into a fraction, begin writing this simple equation:

n = 11.192307 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (2307) and 2 digits in the non-repeating part (19). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 11192307.2307 (equation 2)

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

1000000 × n = 11192307.2307
    100 × n = 11.192307
 999900 × n = 11191188

11191188999900 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 12 (the GCF - greatest common factor).

n = 11191188999900 = 11191188 ÷ 12999900 ÷ 12 = 93259983325. So,

11.192307 = 93259983325 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 93259983325 is also equal to 111602483325 when expressed as a mixed number.
