What is 22.506060606... as a Fraction?

22.506 equals 7427330 as a fraction.

How do you turn 22.506 repeating into a fraction?

Detailed Answer:

Step 1: To convert 22.506 repeating into a fraction, begin writing this simple equation:

n = 22.506 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (06) and 1 digit in the non-repeating part (5). Multiply both sides by 10³ = 1000.

1000 × n = 22506.06 (equation 2)

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

1000 × n = 22506.06
  10 × n = 22.506
 990 × n = 22281

22281990 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 = 22281990 = 22281 ÷ 3990 ÷ 3 = 7427330. So,

22.506 = 7427330 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 7427330 is also equal to 22167330 when expressed as a mixed number.

The repeating decimal 22.506 (vinculum notation) has a repeated block length of 2. It is also represented as 22.5060606... (ellipsis notation) which equals approximately 22.50606060606 (decimal approximation)(*).

The recurring decimal 22.506 can be written as a ratio of two integers having 7427 as the numerator and 330 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.
