A class has 32 students and they all need to present their projects. Every period is 40 minutes long. How many periods will it take for every student to present their project if they have 5 minutes to do so?
All the students will present their projects in 32 * 5 = <<32*5=160>>160 minutes.
It will take 160 / 40 = <<160/40=4>>4 periods for all the students to present their projects.
