How do you turn 3.307 repeating into a fraction?

Detailed Answer:

Step 1: To convert 3.307 repeating into a fraction, begin writing this simple equation:

n = 3.307 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (307), so multiply both sides by 10³ = 1000.

1000 × n = 3307.307 (equation 2)

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

1000 × n = 3307.307
   1 × n = 3.307
 999 × n = 3304

n = 3304999 (answer)

3.307 = 3304999 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 3304999 is also equal to 3307999 when expressed as a mixed number.
