What is 0.8153153153... as a Fraction?

0.8153 equals 181222 as a fraction.

How do you turn 0.8153 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.8153 repeating into a fraction, begin writing this simple equation:

n = 0.8153 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (153) and 1 digit in the non-repeating part (8). Multiply both sides by 10⁴ = 10000.

10000 × n = 8153.153 (equation 2)

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

10000 × n = 8153.153
   10 × n = 0.8153
 9990 × n = 8145

81459990 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 45 (the GCF - greatest common factor).

n = 81459990 = 8145 ÷ 459990 ÷ 45 = 181222. So,

0.8153 = 181222 as the lowest possible fraction.

The repeating decimal 0.8153 (vinculum notation) has a repeated block length of 3. It is also represented as 0.8153153153... (ellipsis notation) which equals approximately 0.8153153153153153 (decimal approximation)(*).

The recurring decimal 0.8153 can be written as a ratio of two integers having 181 as the numerator and 222 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.
