What is 12.083333... as a Fraction?

12.083 equals 14512 as a fraction.

How do you turn 12.083 repeating into a fraction?

Detailed Answer:

Step 1: To convert 12.083 repeating into a fraction, begin writing this simple equation:

n = 12.083 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (08). Multiply both sides by 10³ = 1000.

1000 × n = 12083.3 (equation 2)

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

1000 × n = 12083.3
 100 × n = 12.083
 900 × n = 10875

10875900 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 75 (the GCF - greatest common factor).

n = 10875900 = 10875 ÷ 75900 ÷ 75 = 14512. So,

12.083 = 14512 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 14512 is also equal to 12112 when expressed as a mixed number.

The repeating decimal 12.083 (vinculum notation) has a repeated block length of 1. It is also represented as 12.08333... (ellipsis notation) which equals approximately 12.0833333 (decimal approximation)(*).

The recurring decimal 12.083 can be written as a ratio of two integers having 145 as the numerator and 12 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.
