What is 14.113888... as a Fraction?

14.1138 equals 5081360 as a fraction.

How do you turn 14.1138 repeating into a fraction?

Detailed Answer:

Step 1: To convert 14.1138 repeating into a fraction, begin writing this simple equation:

n = 14.1138 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (8) and 3 digits in the non-repeating part (113). Multiply both sides by 10⁴ = 10000.

10000 × n = 141138.8 (equation 2)

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

10000 × n = 141138.8
 1000 × n = 14.1138
 9000 × n = 127025

1270259000 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 25 (the GCF - greatest common factor).

n = 1270259000 = 127025 ÷ 259000 ÷ 25 = 5081360. So,

14.1138 = 5081360 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 5081360 is also equal to 1441360 when expressed as a mixed number.

The repeating decimal 14.1138 (vinculum notation) has a repeated block length of 1. It is also represented as 14.113888... (ellipsis notation) which equals approximately 14.11388888 (decimal approximation)(*).

The recurring decimal 14.1138 can be written as a ratio of two integers having 5081 as the numerator and 360 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.
