What is 0.132222... as a Fraction?

0.1322 equals 119900 as a fraction.

How do you turn 0.1322 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.1322 repeating into a fraction, begin writing this simple equation:

n = 0.1322 (equation 1)

Step 2: Notice that there is 1 digit in the repeating block (2) and 3 digits in the non-repeating part (132). Multiply both sides by 10⁴ = 10000.

10000 × n = 1322.2 (equation 2)

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

10000 × n = 1322.2
 1000 × n = 0.1322
 9000 × n = 1190

11909000 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 = 11909000 = 1190 ÷ 109000 ÷ 10 = 119900. So,

0.1322 = 119900 as the lowest possible fraction.

The repeating decimal 0.1322 (vinculum notation) has a repeated block length of 1. It is also represented as 0.132222... (ellipsis notation) which equals approximately 0.13222222 (decimal approximation)(*).

The recurring decimal 0.1322 can be written as a ratio of two integers having 119 as the numerator and 900 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.
