1.2307 equals 3409933330 as a fraction.

How do you turn 1.2307 repeating into a fraction?

Detailed Answer:

Step 1: To convert 1.2307 repeating into a fraction, begin writing this simple equation:

n = 1.2307 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (2307), so multiply both sides by 10⁴ = 10000.

10000 × n = 12307.2307 (equation 2)

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

10000 × n = 12307.2307
    1 × n = 1.2307
 9999 × n = 12306

123069999 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 = 123069999 = 12306 ÷ 39999 ÷ 3 = 3409933330. So,

1.2307 = 3409933330 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 3409933330 is also equal to 176933330 when expressed as a mixed number.

The repeating decimal 1.2307 (vinculum notation) has a repeated block length of 4. It is also represented as 1.230723072307... (ellipsis notation) which equals approximately 1.23072307230723072307 (decimal approximation)(*).

The recurring decimal 1.2307 can be written as a ratio of two integers having 34099 as the numerator and 33330 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.
