What is 127.5333... as a Fraction?

127.53 equals 191315 as a fraction.

How do you turn 127.53 repeating into a fraction?

Detailed Answer:

Step 1: To convert 127.53 repeating into a fraction, begin writing this simple equation:

n = 127.53 (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 = 12753.3 (equation 2)

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

100 × n = 12753.3
 10 × n = 127.53
 90 × n = 11478

1147890 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 = 1147890 = 11478 ÷ 690 ÷ 6 = 191315. So,

127.53 = 191315 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 191315 is also equal to 127815 when expressed as a mixed number.

The repeating decimal 127.53 (vinculum notation) has a repeated block length of 1. It is also represented as 127.5333... (ellipsis notation) which equals approximately 127.533333 (decimal approximation)(*).

The recurring decimal 127.53 can be written as a ratio of two integers having 1913 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.
