3/12 = 25%
A fraction like 3/12, or 25%, can show up when three out of twelve people in a group choose the same option. It might also describe a quarter of a pizza, a discount on a purchase, or the portion of a school day spent on one activity.
To picture 3/12 quickly, imagine a whole divided into four equal parts and focus on one of those parts. It is a little less than one-third, so estimating it as about 25% can help you recognize its size.
A common mistake is thinking 3/12 is 3%, because the numerator is 3. The denominator matters too: it tells you the whole is divided into twelve equal parts, making the value one-fourth of the whole.
