What is 10.3292929... as a Fraction?

10.329 equals 5113495 as a fraction.

How do you turn 10.329 repeating into a fraction?

Detailed Answer:

Step 1: To convert 10.329 repeating into a fraction, begin writing this simple equation:

n = 10.329 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (29) and 1 digit in the non-repeating part (3). Multiply both sides by 10³ = 1000.

1000 × n = 10329.29 (equation 2)

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

1000 × n = 10329.29
  10 × n = 10.329
 990 × n = 10226

10226990 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 2 (the GCF - greatest common factor).

n = 10226990 = 10226 ÷ 2990 ÷ 2 = 5113495. So,

10.329 = 5113495 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 5113495 is also equal to 10163495 when expressed as a mixed number.

The repeating decimal 10.329 (vinculum notation) has a repeated block length of 2. It is also represented as 10.3292929... (ellipsis notation) which equals approximately 10.32929292929 (decimal approximation)(*).

The recurring decimal 10.329 can be written as a ratio of two integers having 5113 as the numerator and 495 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.
