Hi there.
This question is written so that you can understand percents using a picture. Percent means "per 100." So they are asking you to color so many squares per 100 of them. In this problem you color 3 squares out of every 20. Since there are five groups of 20 in every 100, you will end up coloring 15 squares (five groups having 3 colored squares). This image indicates that you gave 15% of your money toward your brother's toy.
