What is 17.116161616... as a Fraction?

17.116 equals 3389198 as a fraction.

How do you turn 17.116 repeating into a fraction?

Detailed Answer:

Step 1: To convert 17.116 repeating into a fraction, begin writing this simple equation:

n = 17.116 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (16) and 1 digit in the non-repeating part (1). Multiply both sides by 10³ = 1000.

1000 × n = 17116.16 (equation 2)

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

1000 × n = 17116.16
  10 × n = 17.116
 990 × n = 16945

16945990 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 5 (the GCF - greatest common factor).

n = 16945990 = 16945 ÷ 5990 ÷ 5 = 3389198. So,

17.116 = 3389198 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 3389198 is also equal to 1723198 when expressed as a mixed number.

The repeating decimal 17.116 (vinculum notation) has a repeated block length of 2. It is also represented as 17.1161616... (ellipsis notation) which equals approximately 17.11616161616 (decimal approximation)(*).

The recurring decimal 17.116 can be written as a ratio of two integers having 3389 as the numerator and 198 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.
