How do you turn 2.07692 repeating into a fraction?

Detailed Answer:

Step 1: To convert 2.07692 repeating into a fraction, begin writing this simple equation:

n = 2.07692 (equation 1)

Step 2: Notice that there are 5 digits in the repeating block (07692), so multiply both sides by 10⁵ = 100000.

100000 × n = 207692.07692 (equation 2)

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

100000 × n = 207692.07692
     1 × n = 2.07692
 99999 × n = 207690

20769099999 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 = 20769099999 = 207690 ÷ 399999 ÷ 3 = 6923033333. So,

2.07692 = 6923033333 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 6923033333 is also equal to 2256433333 when expressed as a mixed number.
