How do you turn 16.14230 repeating into a fraction?

Detailed Answer:

Step 1: To convert 16.14230 repeating into a fraction, begin writing this simple equation:

n = 16.14230 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (230) and 2 digits in the non-repeating part (14). Multiply both sides by 10⁵ = 100000.

100000 × n = 1614230.230 (equation 2)

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

100000 × n = 1614230.230
   100 × n = 16.14230
 99900 × n = 1612616

161261699900 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 4 (the GCF - greatest common factor).

n = 161261699900 = 1612616 ÷ 499900 ÷ 4 = 40315424975. So,

16.14230 = 40315424975 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 40315424975 is also equal to 16355424975 when expressed as a mixed number.

The repeating decimal 16.14230 (vinculum notation) has a repeated block length of 3. It is also represented as 16.14230230230... (ellipsis notation) which equals approximately 16.14230230230230230 (decimal approximation)(*).
