How do you turn 14.92857 repeating into a fraction?

Detailed Answer:

Step 1: To convert 14.92857 repeating into a fraction, begin writing this simple equation:

n = 14.92857 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (2857) and 1 digit in the non-repeating part (9). Multiply both sides by 10⁵ = 100000.

100000 × n = 1492857.2857 (equation 2)

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

100000 × n = 1492857.2857
    10 × n = 14.92857
 99990 × n = 1492708

149270899990 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 2 (the GCF - greatest common factor).

n = 149270899990 = 1492708 ÷ 299990 ÷ 2 = 74635449995. So,

14.92857 = 74635449995 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 74635449995 is also equal to 144642449995 when expressed as a mixed number.
