What is 13.101414... as a Fraction?

13.1014 equals 324262475 as a fraction.

How do you turn 13.1014 repeating into a fraction?

Detailed Answer:

Step 1: To convert 13.1014 repeating into a fraction, begin writing this simple equation:

n = 13.1014 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (14) and 2 digits in the non-repeating part (10). Multiply both sides by 10⁴ = 10000.

10000 × n = 131014.14 (equation 2)

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

10000 × n = 131014.14
  100 × n = 13.1014
 9900 × n = 129704

1297049900 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 = 1297049900 = 129704 ÷ 49900 ÷ 4 = 324262475. So,

13.1014 = 324262475 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 324262475 is also equal to 132512475 when expressed as a mixed number.

The repeating decimal 13.1014 (vinculum notation) has a repeated block length of 2. It is also represented as 13.10141414... (ellipsis notation) which equals approximately 13.101414141414 (decimal approximation)(*).

The recurring decimal 13.1014 can be written as a ratio of two integers having 32426 as the numerator and 2475 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.
