What is 0.1072727272... as a Fraction?

0.1072 equals 59550 as a fraction.

How do you turn 0.1072 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.1072 repeating into a fraction, begin writing this simple equation:

n = 0.1072 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (72) and 2 digits in the non-repeating part (10). Multiply both sides by 10⁴ = 10000.

10000 × n = 1072.72 (equation 2)

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

10000 × n = 1072.72
  100 × n = 0.1072
 9900 × n = 1062

10629900 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 18 (the GCF - greatest common factor).

n = 10629900 = 1062 ÷ 189900 ÷ 18 = 59550. So,

0.1072 = 59550 as the lowest possible fraction.

The repeating decimal 0.1072 (vinculum notation) has a repeated block length of 2. It is also represented as 0.10727272... (ellipsis notation) which equals approximately 0.107272727272 (decimal approximation)(*).

The recurring decimal 0.1072 can be written as a ratio of two integers having 59 as the numerator and 550 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.
