What is 22.333... as a Fraction?

22.3 equals 673 as a fraction.

How do you turn 22.3 repeating into a fraction?

Detailed Answer:

Step 1: To convert 22.3 repeating into a fraction, begin writing this simple equation:

n = 22.3 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3), so multiply both sides by 10¹ = 10.

10 × n = 223.3 (equation 2)

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

10 × n = 223.3
 1 × n = 22.3
 9 × n = 201

2019 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 = 2019 = 201 ÷ 39 ÷ 3 = 673. So,

22.3 = 673 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 673 is also equal to 2213 when expressed as a mixed number.

The repeating decimal 22.3 (vinculum notation) has a repeated block length of 1. It is also represented as 22.333... (ellipsis notation) which equals approximately 22.33333 (decimal approximation)(*).

The recurring decimal 22.3 can be written as a ratio of two integers having 67 as the numerator and 3 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.
