12/48 = 25%
A value like 12/48, or 25%, can show up when one-fourth of something is used or completed. For example, 12 out of 48 students might choose the same after-school activity, or a store might offer a discount on one-quarter of its items.
You can picture 25% as one out of four equal parts. To estimate it quickly, imagine dividing a group into four even sections and checking whether the amount is about one section.
A common mistake is thinking 25% means 25 out of 100 items in every situation. It always means one-fourth of the total, so the actual number can change depending on how large the whole group is.
