How do you turn 3.076 repeating into a fraction?

Detailed Answer:

Step 1: To convert 3.076 repeating into a fraction, begin writing this simple equation:

n = 3.076 (equation 1)

Step 2: Notice that there are 3 digits in the repeating block (076), so multiply both sides by 10³ = 1000.

1000 × n = 3076.076 (equation 2)

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

1000 × n = 3076.076
   1 × n = 3.076
 999 × n = 3073

n = 3073999 (answer)

3.076 = 3073999 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 3073999 is also equal to 376999 when expressed as a mixed number.
