What is 53.116... as a Fraction?

53.116 equals 318760 as a fraction.

How do you turn 53.116 repeating into a fraction?

Detailed Answer:

Step 1: To convert 53.116 repeating into a fraction, begin writing this simple equation:

n = 53.116 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (6) and 2 digits in the non-repeating part (11). Multiply both sides by 10³ = 1000.

1000 × n = 53116.6 (equation 2)

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

1000 × n = 53116.6
 100 × n = 53.116
 900 × n = 47805

47805900 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 = 47805900 = 47805 ÷ 15900 ÷ 15 = 318760. So,

53.116 = 318760 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 318760 is also equal to 53760 when expressed as a mixed number.

The repeating decimal 53.116 (vinculum notation) has a repeated block length of 1. It is also represented as 53.11666... (ellipsis notation) which equals approximately 53.1166666 (decimal approximation)(*).

The recurring decimal 53.116 can be written as a ratio of two integers having 3187 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.
