What is 0.72307230723072307... as a Fraction?

0.72307 equals 24103333 as a fraction.

How do you turn 0.72307 repeating into a fraction?

Detailed Answer:

Step 1: To convert 0.72307 repeating into a fraction, begin writing this simple equation:

n = 0.72307 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (2307) and 1 digit in the non-repeating part (7). Multiply both sides by 10⁵ = 100000.

100000 × n = 72307.2307 (equation 2)

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

100000 × n = 72307.2307
    10 × n = 0.72307
 99990 × n = 72300

7230099990 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 30 (the GCF - greatest common factor).

n = 7230099990 = 72300 ÷ 3099990 ÷ 30 = 24103333. So,

0.72307 = 24103333 as the lowest possible fraction.
