What is 105.8333... as a Fraction?

105.83 equals 6356 as a fraction.

How do you turn 105.83 repeating into a fraction?

Detailed Answer:

Step 1: To convert 105.83 repeating into a fraction, begin writing this simple equation:

n = 105.83 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 1 digit in the non-repeating part (8). Multiply both sides by 10² = 100.

100 × n = 10583.3 (equation 2)

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

100 × n = 10583.3
 10 × n = 105.83
 90 × n = 9525

952590 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 = 952590 = 9525 ÷ 1590 ÷ 15 = 6356. So,

105.83 = 6356 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 6356 is also equal to 10556 when expressed as a mixed number.

The repeating decimal 105.83 (vinculum notation) has a repeated block length of 1. It is also represented as 105.8333... (ellipsis notation) which equals approximately 105.833333 (decimal approximation)(*).

The recurring decimal 105.83 can be written as a ratio of two integers having 635 as the numerator and 6 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.
