What is 23.436363636... as a Fraction?

23.436 equals 128955 as a fraction.

How do you turn 23.436 repeating into a fraction?

Detailed Answer:

Step 1: To convert 23.436 repeating into a fraction, begin writing this simple equation:

n = 23.436 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (36) and 1 digit in the non-repeating part (4). Multiply both sides by 10³ = 1000.

1000 × n = 23436.36 (equation 2)

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

1000 × n = 23436.36
  10 × n = 23.436
 990 × n = 23202

23202990 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 18 (the GCF - greatest common factor).

n = 23202990 = 23202 ÷ 18990 ÷ 18 = 128955. So,

23.436 = 128955 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 128955 is also equal to 232455 when expressed as a mixed number.

The repeating decimal 23.436 (vinculum notation) has a repeated block length of 2. It is also represented as 23.4363636... (ellipsis notation) which equals approximately 23.43636363636 (decimal approximation)(*).

The recurring decimal 23.436 can be written as a ratio of two integers having 1289 as the numerator and 55 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.
