What is 10.0285285285... as a Fraction?

10.285 equals 6679666 as a fraction.

How do you turn 10.285 repeating into a fraction?

Detailed Answer:

Step 1: To convert 10.285 repeating into a fraction, begin writing this simple equation:

n = 10.285 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (285), so multiply both sides by 10³ = 1000.

1000 × n = 10285.285 (equation 2)

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

1000 × n = 10285.285
   1 × n = 10.285
 999 × n = 10275

10275999 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 = 10275999 = 10275 ÷ 3999 ÷ 3 = 6679666. So,

10.285 = 6679666 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 6679666 is also equal to 1019666 when expressed as a mixed number.

The repeating decimal 10.285 (vinculum notation) has a repeated block length of 3. It is also represented as 10.285285285... (ellipsis notation) which equals approximately 10.285285285285285 (decimal approximation)(*).

The recurring decimal 10.285 can be written as a ratio of two integers having 6679 as the numerator and 666 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.
