What is 15.23333... as a Fraction?

15.233 equals 45730 as a fraction.

How do you turn 15.233 repeating into a fraction?

Detailed Answer:

Step 1: To convert 15.233 repeating into a fraction, begin writing this simple equation:

n = 15.233 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (23). Multiply both sides by 10³ = 1000.

1000 × n = 15233.3 (equation 2)

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

1000 × n = 15233.3
 100 × n = 15.233
 900 × n = 13710

13710900 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 30 (the GCF - greatest common factor).

n = 13710900 = 13710 ÷ 30900 ÷ 30 = 45730. So,

15.233 = 45730 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 45730 is also equal to 15730 when expressed as a mixed number.

The repeating decimal 15.233 (vinculum notation) has a repeated block length of 1. It is also represented as 15.23333... (ellipsis notation) which equals approximately 15.2333333 (decimal approximation)(*).

The recurring decimal 15.233 can be written as a ratio of two integers having 457 as the numerator and 30 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.
