How do you turn 13.95714 repeating into a fraction?

Detailed Answer:

Step 1: To convert 13.95714 repeating into a fraction, begin writing this simple equation:

n = 13.95714 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (5714) and 1 digit in the non-repeating part (9). Multiply both sides by 10⁵ = 100000.

100000 × n = 1395714.5714 (equation 2)

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

100000 × n = 1395714.5714
    10 × n = 13.95714
 99990 × n = 1395575

139557599990 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 5 (the GCF - greatest common factor).

n = 139557599990 = 1395575 ÷ 599990 ÷ 5 = 27911519998. So,

13.95714 = 27911519998 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 27911519998 is also equal to 131914119998 when expressed as a mixed number.
