How do you turn 16.62307 repeating into a fraction?

Detailed Answer:

Step 1: To convert 16.62307 repeating into a fraction, begin writing this simple equation:

n = 16.62307 (equation 1)

Step 2: Notice that there are 4 digits in the repeating block (2307) and 1 digit in the non-repeating part (6). Multiply both sides by 10⁵ = 100000.

100000 × n = 1662307.2307 (equation 2)

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

100000 × n = 1662307.2307
    10 × n = 16.62307
 99990 × n = 1662141

166214199990 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 = 166214199990 = 1662141 ÷ 399990 ÷ 3 = 55404733330. So,

16.62307 = 55404733330 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 55404733330 is also equal to 162076733330 when expressed as a mixed number.
