What is 2.32828... as a Fraction?

2.328 equals 461198 as a fraction.

How do you turn 2.328 repeating into a fraction?

Detailed Answer:

Step 1: To convert 2.328 repeating into a fraction, begin writing this simple equation:

n = 2.328 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (28) and 1 digit in the non-repeating part (3). Multiply both sides by 10³ = 1000.

1000 × n = 2328.28 (equation 2)

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

1000 × n = 2328.28
  10 × n = 2.328
 990 × n = 2305

2305990 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 5 (the GCF - greatest common factor).

n = 2305990 = 2305 ÷ 5990 ÷ 5 = 461198. So,

2.328 = 461198 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 461198 is also equal to 265198 when expressed as a mixed number.

The repeating decimal 2.328 (vinculum notation) has a repeated block length of 2. It is also represented as 2.3282828... (ellipsis notation) which equals approximately 2.32828282828 (decimal approximation)(*).

The recurring decimal 2.328 can be written as a ratio of two integers having 461 as the numerator and 198 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.
