What is 9.110606... as a Fraction?

9.1106 equals 6013660 as a fraction.

How do you turn 9.1106 repeating into a fraction?

Detailed Answer:

Step 1: To convert 9.1106 repeating into a fraction, begin writing this simple equation:

n = 9.1106 (equation 1)

Step 2: Notice that there are 2 digits in the repeating block (06) and 2 digits in the non-repeating part (11). Multiply both sides by 10⁴ = 10000.

10000 × n = 91106.06 (equation 2)

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

10000 × n = 91106.06
  100 × n = 9.1106
 9900 × n = 90195

901959900 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 15 (the GCF - greatest common factor).

n = 901959900 = 90195 ÷ 159900 ÷ 15 = 6013660. So,

9.1106 = 6013660 as the lowest possible fraction.

As the numerator is greater than the denominator, we have an improper fraction, so we can also express it as a mixed number, thus 6013660 is also equal to 973660 when expressed as a mixed number.

The repeating decimal 9.1106 (vinculum notation) has a repeated block length of 2. It is also represented as 9.11060606... (ellipsis notation) which equals approximately 9.110606060606 (decimal approximation)(*).

The recurring decimal 9.1106 can be written as a ratio of two integers having 6013 as the numerator and 660 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.
