What is 11.3838383... as a Fraction?

11.383 equals 112799 as a fraction.

How do you turn 11.383 repeating into a fraction?

Detailed Answer:

Step 1: To convert 11.383 repeating into a fraction, begin writing this simple equation:

n = 11.383 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (83) and 1 digit in the non-repeating part (3). Multiply both sides by 10³ = 1000.

1000 × n = 11383.83 (equation 2)

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

1000 × n = 11383.83
  10 × n = 11.383
 990 × n = 11270

11270990 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 10 (the GCF - greatest common factor).

n = 11270990 = 11270 ÷ 10990 ÷ 10 = 112799. So,

11.383 = 112799 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 112799 is also equal to 113899 when expressed as a mixed number.

The repeating decimal 11.383 (vinculum notation) has a repeated block length of 2. It is also represented as 11.3838383... (ellipsis notation) which equals approximately 11.38383838383 (decimal approximation)(*).

The recurring decimal 11.383 can be written as a ratio of two integers having 1127 as the numerator and 99 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.
