What is 55.3166... as a Fraction?

55.316 equals 331960 as a fraction.

How do you turn 55.316 repeating into a fraction?

Detailed Answer:

Step 1: To convert 55.316 repeating into a fraction, begin writing this simple equation:

n = 55.316 (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 = 55316.6 (equation 2)

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

1000 × n = 55316.6
 100 × n = 55.316
 900 × n = 49785

49785900 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 = 49785900 = 49785 ÷ 15900 ÷ 15 = 331960. So,

55.316 = 331960 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 331960 is also equal to 551960 when expressed as a mixed number.

The repeating decimal 55.316 (vinculum notation) has a repeated block length of 1. It is also represented as 55.31666... (ellipsis notation) which equals approximately 55.3166666 (decimal approximation)(*).

The recurring decimal 55.316 can be written as a ratio of two integers having 3319 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.
