13.2654 equals 3648275 as a fraction.

How do you turn 13.2654 repeating into a fraction?

Detailed Answer:

Step 1: To convert 13.2654 repeating into a fraction, begin writing this simple equation:

n = 13.2654 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (54) and 2 digits in the non-repeating part (26). Multiply both sides by 10⁴ = 10000.

10000 × n = 132654.54 (equation 2)

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

10000 × n = 132654.54
  100 × n = 13.2654
 9900 × n = 131328

1313289900 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 36 (the GCF - greatest common factor).

n = 1313289900 = 131328 ÷ 369900 ÷ 36 = 3648275. So,

13.2654 = 3648275 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 3648275 is also equal to 1373275 when expressed as a mixed number.

The repeating decimal 13.2654 (vinculum notation) has a repeated block length of 2. It is also represented as 13.26545454... (ellipsis notation) which equals approximately 13.265454545454 (decimal approximation)(*).

The recurring decimal 13.2654 can be written as a ratio of two integers having 3648 as the numerator and 275 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.
