What is 0.1636363... as a Fraction?

0.163 equals 955 as a fraction.

How do you turn 0.163 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.163 repeating into a fraction, begin writing this simple equation:

n = 0.163 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (63) and 1 digit in the non-repeating part (1). Multiply both sides by 10³ = 1000.

1000 × n = 163.63 (equation 2)

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

1000 × n = 163.63
  10 × n = 0.163
 990 × n = 162

162990 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 = 162990 = 162 ÷ 18990 ÷ 18 = 955. So,

0.163 = 955 as the lowest possible fraction.

The repeating decimal 0.163 (vinculum notation) has a repeated block length of 2. It is also represented as 0.1636363... (ellipsis notation) which equals approximately 0.16363636363 (decimal approximation)(*).

The recurring decimal 0.163 can be written as a ratio of two integers having 9 as the numerator and 55 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.

(*) At present, there is no single universally accepted notation or phrasing for repeating decimals.
