17.1027 equals 188131100 as a fraction.

How do you turn 17.1027 repeating into a fraction?

Detailed Answer:

Step 1: To convert 17.1027 repeating into a fraction, begin writing this simple equation:

n = 17.1027 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (27) and 2 digits in the non-repeating part (10). Multiply both sides by 10⁴ = 10000.

10000 × n = 171027.27 (equation 2)

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

10000 × n = 171027.27
  100 × n = 17.1027
 9900 × n = 169317

1693179900 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 = 1693179900 = 169317 ÷ 99900 ÷ 9 = 188131100. So,

17.1027 = 188131100 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 188131100 is also equal to 171131100 when expressed as a mixed number.

The repeating decimal 17.1027 (vinculum notation) has a repeated block length of 2. It is also represented as 17.10272727... (ellipsis notation) which equals approximately 17.102727272727 (decimal approximation)(*).

The recurring decimal 17.1027 can be written as a ratio of two integers having 18813 as the numerator and 1100 as the denominator. So, it is a rational number (named after ratio). It can be shown that a number is rational if its decimal representation is repeating or terminating.
