What is 342.18333... as a Fraction?

342.183 equals 2053160 as a fraction.

How do you turn 342.183 repeating into a fraction?

Detailed Answer:

Step 1: To convert 342.183 repeating into a fraction, begin writing this simple equation:

n = 342.183 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (18). Multiply both sides by 10³ = 1000.

1000 × n = 342183.3 (equation 2)

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

1000 × n = 342183.3
 100 × n = 342.183
 900 × n = 307965

307965900 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 15 (the GCF - greatest common factor).

n = 307965900 = 307965 ÷ 15900 ÷ 15 = 2053160. So,

342.183 = 2053160 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 2053160 is also equal to 3421160 when expressed as a mixed number.

The repeating decimal 342.183 (vinculum notation) has a repeated block length of 1. It is also represented as 342.18333... (ellipsis notation) which equals approximately 342.1833333 (decimal approximation)(*).

The recurring decimal 342.183 can be written as a ratio of two integers having 20531 as the numerator and 60 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.
