If you're still having trouble understanding what a percentage represents, stop and watch the video before you keep going.

Part 2

Use the simulation to explore the following question. 200 people attended a concert. Forty percent of them were seated on the floor. How many individuals were seated on the floor? Hint: Think about what the part, whole, and percentage should be in this problem.

How many people were seated on the floor?

Part 3

In science, we often use percentages without communicating specifically what they mean. For example when someone says 52% of people got the flu vaccine this year, we only know the part, not the whole. With your group, come up with three possible groups of people that could represent the whole in this percentage. List them here.

Can you think of a time someone has told you a percentage without specifying the whole? If yes, share it below. If not, think about a scenario in which that could happen.

Why do you think it is important to be specific when we communicate percentages to others? In other words, why should we be clear about the part, whole, and percentage?
