What is 56.3166... as a Fraction?

56.316 equals 337960 as a fraction.

How do you turn 56.316 repeating into a fraction?

Detailed Answer:

Step 1: To convert 56.316 repeating into a fraction, begin writing this simple equation:

n = 56.316 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (6) and 2 digits in the non-repeating part (31). Multiply both sides by 10³ = 1000.

1000 × n = 56316.6 (equation 2)

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

1000 × n = 56316.6
 100 × n = 56.316
 900 × n = 50685

50685900 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 15 (the GCF - greatest common factor).

n = 50685900 = 50685 ÷ 15900 ÷ 15 = 337960. So,

56.316 = 337960 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 337960 is also equal to 561960 when expressed as a mixed number.

The repeating decimal 56.316 (vinculum notation) has a repeated block length of 1. It is also represented as 56.31666... (ellipsis notation) which equals approximately 56.3166666 (decimal approximation)(*).

The recurring decimal 56.316 can be written as a ratio of two integers having 3379 as the numerator and 60 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.
