What is 0.57171... as a Fraction?

0.571 equals 283495 as a fraction.

How do you turn 0.571 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.571 repeating into a fraction, begin writing this simple equation:

n = 0.571 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (71) and 1 digit in the non-repeating part (5). Multiply both sides by 10³ = 1000.

1000 × n = 571.71 (equation 2)

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

1000 × n = 571.71
  10 × n = 0.571
 990 × n = 566

566990 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 2 (the GCF - greatest common factor).

n = 566990 = 566 ÷ 2990 ÷ 2 = 283495. So,

0.571 = 283495 as the lowest possible fraction.

The repeating decimal 0.571 (vinculum notation) has a repeated block length of 2. It is also represented as 0.5717171... (ellipsis notation) which equals approximately 0.57171717171 (decimal approximation)(*).

The recurring decimal 0.571 can be written as a ratio of two integers having 283 as the numerator and 495 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.
