80% of the students in Lea’s class earned an A or a B on the weekly math test. If 20 students got an A or a B, how many students are in Lea’s class?
20 is 80% of what number?
20 × 4 = 80, so 100 × 4 = 400 students
20 + 60 = 80, so 100 + 60 = 160 students
80 ÷ 4 = 20, so 100 ÷ 4 = 25 students
80 – 60 = 20, so 100 – 60 = 40 students
