How do you turn 11.11714285 repeating into a fraction?

Detailed Answer:

Step 1: To convert 11.11714285 repeating into a fraction, begin writing this simple equation:

n = 11.11714285 (equation 1)

Step 2: Notice that there are 6 digits in the repeating block (714285) and 2 digits in the non-repeating part (11). Multiply both sides by 10⁸ = 100000000.

100000000 × n = 1111714285.714285 (equation 2)

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

100000000 × n = 1111714285.714285
      100 × n = 11.11714285
 99999900 × n = 1111713174

111171317499999900 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 285714 (the GCF - greatest common factor).

n = 111171317499999900 = 1111713174 ÷ 28571499999900 ÷ 285714 = 3891350. So,

11.11714285 = 3891350 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 3891350 is also equal to 1141350 when expressed as a mixed number.
