A fifth grade class of 32 students is going on a field trip. They want to rent vans to drive to the field trip. Each van seats a maximum of 7 students. What is the least number of vans the fifth grade class must rent so that each student has a seat? If I times it that is too many buses 32x7= 224 I know I don't subtract, so do I add which is 39 buses.

Try dividing.

If each van can carry max 7 students, and 32 kids are going, we need 32/7 rounded up. 32/7 = ~4.57 = 5 vans.

You need 5 vans for the minimum to carry all 32 students and guarantee each student has a seat.

The 7th grade classes of 392 students are going on a field trip. They need 4 chaperones for every 28 students. How many adults are needed at the picnic?

To find the least number of vans the fifth grade class must rent so that each student has a seat, you need to divide the total number of students by the maximum capacity of each van.

In this case, you have 32 students, and each van can seat a maximum of 7 students. To calculate the number of vans needed, you divide 32 by 7.

32 ÷ 7 = 4.57

Since you cannot have a fraction of a van, you need to round up to the next whole number. Therefore, the fifth grade class must rent at least 5 vans so that each student has a seat.

You do not need to multiply or add in this case because multiplication is used to find the total capacity (maximum number of students) and addition is used when you need to combine different quantities. In this scenario, you are dividing the total number of students by the maximum number of students that can be accommodated in a single van.
