What is 349.133... as a Fraction?

349.133 equals 523715 as a fraction.

How do you turn 349.133 repeating into a fraction?

Detailed Answer:

Step 1: To convert 349.133 repeating into a fraction, begin writing this simple equation:

n = 349.133 (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 = 349133.3 (equation 2)

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

1000 × n = 349133.3
 100 × n = 349.133
 900 × n = 314220

314220900 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 = 314220900 = 314220 ÷ 60900 ÷ 60 = 523715. So,

349.133 = 523715 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 523715 is also equal to 349215 when expressed as a mixed number.

The repeating decimal 349.133 (vinculum notation) has a repeated block length of 1. It is also represented as 349.13333... (ellipsis notation) which equals approximately 349.1333333 (decimal approximation)(*).

The recurring decimal 349.133 can be written as a ratio of two integers having 5237 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.
