What is 0.603030303... as a Fraction?

0.603 equals 199330 as a fraction.

How do you turn 0.603 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.603 repeating into a fraction, begin writing this simple equation:

n = 0.603 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (03) and 1 digit in the non-repeating part (6). Multiply both sides by 10³ = 1000.

1000 × n = 603.03 (equation 2)

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

1000 × n = 603.03
  10 × n = 0.603
 990 × n = 597

597990 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 3 (the GCF - greatest common factor).

n = 597990 = 597 ÷ 3990 ÷ 3 = 199330. So,

0.603 = 199330 as the lowest possible fraction.

The repeating decimal 0.603 (vinculum notation) has a repeated block length of 2. It is also represented as 0.6030303... (ellipsis notation) which equals approximately 0.60303030303 (decimal approximation)(*).

The recurring decimal 0.603 can be written as a ratio of two integers having 199 as the numerator and 330 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.
