What is 13.10444... as a Fraction?

13.104 equals 5897450 as a fraction.

How do you turn 13.104 repeating into a fraction?

Detailed Answer:

Step 1: To convert 13.104 repeating into a fraction, begin writing this simple equation:

n = 13.104 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (4) and 2 digits in the non-repeating part (10). Multiply both sides by 10³ = 1000.

1000 × n = 13104.4 (equation 2)

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

1000 × n = 13104.4
 100 × n = 13.104
 900 × n = 11794

11794900 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 2 (the GCF - greatest common factor).

n = 11794900 = 11794 ÷ 2900 ÷ 2 = 5897450. So,

13.104 = 5897450 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 5897450 is also equal to 1347450 when expressed as a mixed number.

The repeating decimal 13.104 (vinculum notation) has a repeated block length of 1. It is also represented as 13.10444... (ellipsis notation) which equals approximately 13.1044444 (decimal approximation)(*).

The recurring decimal 13.104 can be written as a ratio of two integers having 5897 as the numerator and 450 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.
