What is 11.58888... as a Fraction?

11.588 equals 104390 as a fraction.

How do you turn 11.588 repeating into a fraction?

Detailed Answer:

Step 1: To convert 11.588 repeating into a fraction, begin writing this simple equation:

n = 11.588 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (8) and 2 digits in the non-repeating part (58). Multiply both sides by 10³ = 1000.

1000 × n = 11588.8 (equation 2)

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

1000 × n = 11588.8
 100 × n = 11.588
 900 × n = 10430

10430900 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 10 (the GCF - greatest common factor).

n = 10430900 = 10430 ÷ 10900 ÷ 10 = 104390. So,

11.588 = 104390 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 104390 is also equal to 115390 when expressed as a mixed number.

The repeating decimal 11.588 (vinculum notation) has a repeated block length of 1. It is also represented as 11.58888... (ellipsis notation) which equals approximately 11.5888888 (decimal approximation)(*).

The recurring decimal 11.588 can be written as a ratio of two integers having 1043 as the numerator and 90 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.
