What is 342.22333... as a Fraction?

342.223 equals 102667300 as a fraction.

How do you turn 342.223 repeating into a fraction?

Detailed Answer:

Step 1: To convert 342.223 repeating into a fraction, begin writing this simple equation:

n = 342.223 (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 = 342223.3 (equation 2)

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

1000 × n = 342223.3
 100 × n = 342.223
 900 × n = 308001

308001900 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 = 308001900 = 308001 ÷ 3900 ÷ 3 = 102667300. So,

342.223 = 102667300 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 102667300 is also equal to 34267300 when expressed as a mixed number.

The repeating decimal 342.223 (vinculum notation) has a repeated block length of 1. It is also represented as 342.22333... (ellipsis notation) which equals approximately 342.2233333 (decimal approximation)(*).

The recurring decimal 342.223 can be written as a ratio of two integers having 102667 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.
