How do you turn 3.107692 repeating into a fraction?

Detailed Answer:

Step 1: To convert 3.107692 repeating into a fraction, begin writing this simple equation:

n = 3.107692 (equation 1)

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

1000000 × n = 3107692.07692 (equation 2)

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

1000000 × n = 3107692.07692
     10 × n = 3.107692
 999990 × n = 3107661

3107661999990 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 = 3107661999990 = 3107661 ÷ 3999990 ÷ 3 = 1035887333330. So,

3.107692 = 1035887333330 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 1035887333330 is also equal to 335897333330 when expressed as a mixed number.
