How do you turn 14.54615 repeating into a fraction?

Detailed Answer:

Step 1: To convert 14.54615 repeating into a fraction, begin writing this simple equation:

n = 14.54615 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (4615) and 1 digit in the non-repeating part (5). Multiply both sides by 10⁵ = 100000.

100000 × n = 1454615.4615 (equation 2)

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

100000 × n = 1454615.4615
    10 × n = 14.54615
 99990 × n = 1454470

145447099990 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 10 (the GCF - greatest common factor).

n = 145447099990 = 1454470 ÷ 1099990 ÷ 10 = 1454479999. So,

14.54615 = 1454479999 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 1454479999 is also equal to 1454619999 when expressed as a mixed number.
