4/100 = 4%
A value like 4/100, or 4%, can show up in everyday life as a small discount, a chance of rain, or the portion of students in a school who share a certain trait. It is small enough to matter but usually does not affect the whole group very much.
To picture 4%, imagine 4 shaded squares in a grid of 100 equal squares. You can also estimate it as about 1 out of every 25 items, which makes it easier to understand when looking at a large group.
A common mistake is thinking 4% means 4 whole items instead of 4 parts out of every 100. The actual number depends on the total amount, so 4% of 100 people is different from 4% of 1,000 people.
