12/390 = ≈3.08%
Rounded to 2 decimal places.
A fraction like 12/390 can show up in everyday life when 12 items out of a group of 390 meet a certain condition. For example, 12 customers in a survey might choose the same unusual option, which represents 3.08% of everyone surveyed.
To picture this amount, imagine 100 people lined up and only about 3 of them being selected. Since 3.08% is just a little more than 3%, you can estimate it quickly as roughly 3 out of every 100.
One common mistake is thinking that 12 out of 390 is close to 12%, because the numerator is 12. The denominator matters just as much, and a group of 390 makes the fraction much smaller than 12 out of 100.
