19.824 equals 3271165 as a fraction.

How do you turn 19.824 repeating into a fraction?

Detailed Answer:

Step 1: To convert 19.824 repeating into a fraction, begin writing this simple equation:

n = 19.824 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (24) and 1 digit in the non-repeating part (8). Multiply both sides by 10³ = 1000.

1000 × n = 19824.24 (equation 2)

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

1000 × n = 19824.24
  10 × n = 19.824
 990 × n = 19626

19626990 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 6 (the GCF - greatest common factor).

n = 19626990 = 19626 ÷ 6990 ÷ 6 = 3271165. So,

19.824 = 3271165 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 3271165 is also equal to 19136165 when expressed as a mixed number.

The repeating decimal 19.824 (vinculum notation) has a repeated block length of 2. It is also represented as 19.8242424... (ellipsis notation) which equals approximately 19.82424242424 (decimal approximation)(*).

The recurring decimal 19.824 can be written as a ratio of two integers having 3271 as the numerator and 165 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.
