Since each bus holds 52 students, you can find how many buses will be needed by dividing the total number of students by the number of students the buses can hold.
total number students ÷ number students bus can hold = number buses needed
1,056 ÷ 52 = 20.3
We will round this number up because you cannot have a fraction of a bus! 20.3 buses will be rounded to 21 buses.
21 buses will be needed to transport 1,056 students.
