What is 328.1333... as a Fraction?

328.133 equals 492215 as a fraction.

How do you turn 328.133 repeating into a fraction?

Detailed Answer:

Step 1: To convert 328.133 repeating into a fraction, begin writing this simple equation:

n = 328.133 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 2 digits in the non-repeating part (13). Multiply both sides by 10³ = 1000.

1000 × n = 328133.3 (equation 2)

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

1000 × n = 328133.3
 100 × n = 328.133
 900 × n = 295320

295320900 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 60 (the GCF - greatest common factor).

n = 295320900 = 295320 ÷ 60900 ÷ 60 = 492215. So,

328.133 = 492215 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 492215 is also equal to 328215 when expressed as a mixed number.

The repeating decimal 328.133 (vinculum notation) has a repeated block length of 1. It is also represented as 328.13333... (ellipsis notation) which equals approximately 328.1333333 (decimal approximation)(*).

The recurring decimal 328.133 can be written as a ratio of two integers having 4922 as the numerator and 15 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.
