What is 22.45333... as a Fraction?

22.453 equals 168475 as a fraction.

How do you turn 22.453 repeating into a fraction?

Detailed Answer:

Step 1: To convert 22.453 repeating into a fraction, begin writing this simple equation:

n = 22.453 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (45). Multiply both sides by 10³ = 1000.

1000 × n = 22453.3 (equation 2)

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

1000 × n = 22453.3
 100 × n = 22.453
 900 × n = 20208

20208900 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 12 (the GCF - greatest common factor).

n = 20208900 = 20208 ÷ 12900 ÷ 12 = 168475. So,

22.453 = 168475 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 168475 is also equal to 223475 when expressed as a mixed number.

The repeating decimal 22.453 (vinculum notation) has a repeated block length of 1. It is also represented as 22.45333... (ellipsis notation) which equals approximately 22.4533333 (decimal approximation)(*).

The recurring decimal 22.453 can be written as a ratio of two integers having 1684 as the numerator and 75 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.
