How do you turn 3.292307 repeating into a fraction?

Detailed Answer:

Step 1: To convert 3.292307 repeating into a fraction, begin writing this simple equation:

n = 3.292307 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (2307) and 2 digits in the non-repeating part (29). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 3292307.2307 (equation 2)

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

1000000 × n = 3292307.2307
    100 × n = 3.292307
 999900 × n = 3291978

3291978999900 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 6 (the GCF - greatest common factor).

n = 3291978999900 = 3291978 ÷ 6999900 ÷ 6 = 548663166650. So,

3.292307 = 548663166650 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 548663166650 is also equal to 348713166650 when expressed as a mixed number.
