3/100 = 3%
A value like 3/100, or 3%, can show up in everyday life as a small discount, a chance of rain, or the portion of students in a group who choose a certain option. For example, a store might offer 3% off a purchase, which is a noticeable but fairly small savings.
You can picture 3/100 by imagining 100 equal squares with only 3 shaded. As a quick estimate, think of 3% as a little less than one-twentieth, since 5% is one-twentieth.
A common mistake is treating 3% as if it means 3 out of 10 instead of 3 out of 100. That would make the amount ten times larger, so it is important to notice whether the whole is divided into 100 parts.
