How do you turn 13.707692 repeating into a fraction?

Detailed Answer:

Step 1: To convert 13.707692 repeating into a fraction, begin writing this simple equation:

n = 13.707692 (equation 1)

Step 2: Notice that there are 5 digits in the repeating block (07692) and 1 digit in the non-repeating part (7). Multiply both sides by 10⁶ = 1000000.

1000000 × n = 13707692.07692 (equation 2)

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

1000000 × n = 13707692.07692
     10 × n = 13.707692
 999990 × n = 13707555

13707555999990 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 = 13707555999990 = 13707555 ÷ 15999990 ÷ 15 = 91383766666. So,

13.707692 = 91383766666 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 91383766666 is also equal to 134717966666 when expressed as a mixed number.
