What is 22.854545454... as a Fraction?

22.854 equals 125755 as a fraction.

How do you turn 22.854 repeating into a fraction?

Detailed Answer:

Step 1: To convert 22.854 repeating into a fraction, begin writing this simple equation:

n = 22.854 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (54) and 1 digit in the non-repeating part (8). Multiply both sides by 10³ = 1000.

1000 × n = 22854.54 (equation 2)

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

1000 × n = 22854.54
  10 × n = 22.854
 990 × n = 22626

22626990 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 = 22626990 = 22626 ÷ 18990 ÷ 18 = 125755. So,

22.854 = 125755 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 125755 is also equal to 224755 when expressed as a mixed number.

The repeating decimal 22.854 (vinculum notation) has a repeated block length of 2. It is also represented as 22.8545454... (ellipsis notation) which equals approximately 22.85454545454 (decimal approximation)(*).

The recurring decimal 22.854 can be written as a ratio of two integers having 1257 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.
