What is 0.5454... as a Fraction?

0.54 equals 611 as a fraction.

How do you turn 0.54 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.54 repeating into a fraction, begin writing this simple equation:

n = 0.54 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (54), so multiply both sides by 10² = 100.

100 × n = 54.54 (equation 2)

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

100 × n = 54.54
  1 × n = 0.54
 99 × n = 54

5499 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 = 5499 = 54 ÷ 999 ÷ 9 = 611. So,

0.54 = 611 as the lowest possible fraction.

The repeating decimal 0.54 (vinculum notation) has a repeated block length of 2. It is also represented as 0.545454... (ellipsis notation) which equals approximately 0.5454545454 (decimal approximation)(*).

The recurring decimal 0.54 can be written as a ratio of two integers having 6 as the numerator and 11 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.
