What is 58.566... as a Fraction?

58.56 equals 175730 as a fraction.

How do you turn 58.56 repeating into a fraction?

Detailed Answer:

Step 1: To convert 58.56 repeating into a fraction, begin writing this simple equation:

n = 58.56 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (6) and 1 digit in the non-repeating part (5). Multiply both sides by 10² = 100.

100 × n = 5856.6 (equation 2)

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

100 × n = 5856.6
 10 × n = 58.56
 90 × n = 5271

527190 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 3 (the GCF - greatest common factor).

n = 527190 = 5271 ÷ 390 ÷ 3 = 175730. So,

58.56 = 175730 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 175730 is also equal to 581730 when expressed as a mixed number.

The repeating decimal 58.56 (vinculum notation) has a repeated block length of 1. It is also represented as 58.5666... (ellipsis notation) which equals approximately 58.566666 (decimal approximation)(*).

The recurring decimal 58.56 can be written as a ratio of two integers having 1757 as the numerator and 30 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.
