What is 3.110333... as a Fraction?

3.1103 equals 93313000 as a fraction.

How do you turn 3.1103 repeating into a fraction?

Detailed Answer:

Step 1: To convert 3.1103 repeating into a fraction, begin writing this simple equation:

n = 3.1103 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 3 digits in the non-repeating part (110). Multiply both sides by 10⁴ = 10000.

10000 × n = 31103.3 (equation 2)

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

10000 × n = 31103.3
 1000 × n = 3.1103
 9000 × n = 27993

279939000 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 3 (the GCF - greatest common factor).

n = 279939000 = 27993 ÷ 39000 ÷ 3 = 93313000. So,

3.1103 = 93313000 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 93313000 is also equal to 33313000 when expressed as a mixed number.

The repeating decimal 3.1103 (vinculum notation) has a repeated block length of 1. It is also represented as 3.110333... (ellipsis notation) which equals approximately 3.11033333 (decimal approximation)(*).

The recurring decimal 3.1103 can be written as a ratio of two integers having 9331 as the numerator and 3000 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.
