There were 170 students going on a field trip. Each van can carry 15 students. To determine how many vans are needed, the calculation of 170 students divided by 15 students per van is done, with the remainder showing that 11 vans plus 5 extra students are needed to transport all 170 students.

1. 170 students are going to the museum. Each van carries 15 students. How many vans are needed? 15 x 10 = 150 150 + 15 = 165 15 x 11 = 165 170 - 165 = 5 So the answer is 11 R.5 15 15 15 170 15 = . .
