What is 329.213... as a Fraction?

329.213 equals 2469175 as a fraction.

How do you turn 329.213 repeating into a fraction?

Detailed Answer:

Step 1: To convert 329.213 repeating into a fraction, begin writing this simple equation:

n = 329.213 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (21). Multiply both sides by 10³ = 1000.

1000 × n = 329213.3 (equation 2)

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

1000 × n = 329213.3
 100 × n = 329.213
 900 × n = 296292

296292900 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 = 296292900 = 296292 ÷ 12900 ÷ 12 = 2469175. So,

329.213 = 2469175 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 2469175 is also equal to 3291675 when expressed as a mixed number.

The repeating decimal 329.213 (vinculum notation) has a repeated block length of 1. It is also represented as 329.21333... (ellipsis notation) which equals approximately 329.2133333 (decimal approximation)(*).

The recurring decimal 329.213 can be written as a ratio of two integers having 24691 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.
