What is 0.0153153153... as a Fraction?

0.153 equals 171110 as a fraction.

How do you turn 0.153 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.153 repeating into a fraction, begin writing this simple equation:

n = 0.153 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (153), so multiply both sides by 10³ = 1000.

1000 × n = 153.153 (equation 2)

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

1000 × n = 153.153
   1 × n = 0.153
 999 × n = 153

153999 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 9 (the GCF - greatest common factor).

n = 153999 = 153 ÷ 9999 ÷ 9 = 171110. So,

0.153 = 171110 as the lowest possible fraction.

The repeating decimal 0.153 (vinculum notation) has a repeated block length of 3. It is also represented as 0.153153153... (ellipsis notation) which equals approximately 0.153153153153153 (decimal approximation)(*).

The recurring decimal 0.153 can be written as a ratio of two integers having 17 as the numerator and 1110 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.
