What is 82.5333... as a Fraction?

82.53 equals 123815 as a fraction.

How do you turn 82.53 repeating into a fraction?

Detailed Answer:

Step 1: To convert 82.53 repeating into a fraction, begin writing this simple equation:

n = 82.53 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (3) and 1 digit in the non-repeating part (5). Multiply both sides by 10² = 100.

100 × n = 8253.3 (equation 2)

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

100 × n = 8253.3
 10 × n = 82.53
 90 × n = 7428

742890 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 6 (the GCF - greatest common factor).

n = 742890 = 7428 ÷ 690 ÷ 6 = 123815. So,

82.53 = 123815 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 123815 is also equal to 82815 when expressed as a mixed number.

The repeating decimal 82.53 (vinculum notation) has a repeated block length of 1. It is also represented as 82.5333... (ellipsis notation) which equals approximately 82.533333 (decimal approximation)(*).

The recurring decimal 82.53 can be written as a ratio of two integers having 1238 as the numerator and 15 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.
