What is 16.2063636363... as a Fraction?

16.2063 equals 178271100 as a fraction.

How do you turn 16.2063 repeating into a fraction?

Detailed Answer:

Step 1: To convert 16.2063 repeating into a fraction, begin writing this simple equation:

n = 16.2063 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (63) and 2 digits in the non-repeating part (20). Multiply both sides by 10⁴ = 10000.

10000 × n = 162063.63 (equation 2)

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

10000 × n = 162063.63
  100 × n = 16.2063
 9900 × n = 160443

1604439900 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 9 (the GCF - greatest common factor).

n = 1604439900 = 160443 ÷ 99900 ÷ 9 = 178271100. So,

16.2063 = 178271100 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 178271100 is also equal to 162271100 when expressed as a mixed number.

The repeating decimal 16.2063 (vinculum notation) has a repeated block length of 2. It is also represented as 16.20636363... (ellipsis notation) which equals approximately 16.206363636363 (decimal approximation)(*).
