18/100 = 18%
The fraction 18/100, or 18%, can show up in everyday life when 18 out of every 100 people, items, or points are involved. For example, a store might advertise an 18% discount, or a survey might report that 18% of students prefer a certain activity.
You can picture 18% as a little less than one-fifth of a whole. On a group of 100 objects, imagine shading 18 of them, or estimate it as about 20 out of 100 for a quick mental comparison.
A common mistake is treating 18% as if it means 18 whole items no matter what the total is. The actual amount depends on the size of the group, so 18% of 100 is much smaller than 18% of 1,000.
