30/200 = 15%
A value like 30/200, or 15%, can show up in everyday life when 30 out of 200 people choose a certain option. It might describe the share of students who ride the bus, customers who buy a product, or items in a store that are on sale.
To picture 15% quickly, imagine 15 out of every 100 objects, or about 1.5 objects out of every 10. It is a little less than one-sixth of a group, so you can estimate it as a small but noticeable portion.
A common mistake is thinking 15% means 15 items no matter how large the group is. The actual number depends on the total, so 15% of 200 is much more than 15% of 20.
