Final answer:
Harriet can find out how many stops the bus made by dividing the total number of students on the bus by the number of students who got off at one stop.
Step-by-step explanation:
To find out how many stops the bus made, Harriet can divide the total number of students on the bus by the number of students who got off at one stop.
Let's say Harriet saw that 8 students got off at one stop. If there are 36 students on the bus, we can divide 36 by 8 to find out how many stops the bus made.
36 รท 8 = 4
Therefore, the bus made 4 stops.
