What is 30.2233... as a Fraction?

30.223 equals 9067300 as a fraction.

How do you turn 30.223 repeating into a fraction?

Detailed Answer:

Step 1: To convert 30.223 repeating into a fraction, begin writing this simple equation:

n = 30.223 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (22). Multiply both sides by 10³ = 1000.

1000 × n = 30223.3 (equation 2)

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

1000 × n = 30223.3
 100 × n = 30.223
 900 × n = 27201

27201900 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 = 27201900 = 27201 ÷ 3900 ÷ 3 = 9067300. So,

30.223 = 9067300 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 9067300 is also equal to 3067300 when expressed as a mixed number.

The repeating decimal 30.223 (vinculum notation) has a repeated block length of 1. It is also represented as 30.22333... (ellipsis notation) which equals approximately 30.2233333 (decimal approximation)(*).

The recurring decimal 30.223 can be written as a ratio of two integers having 9067 as the numerator and 300 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.
