there are 56 students going to the game. the coach puts 7 students in each van. which number sentence can be used to find out how many vans are needed to take the students to the game?

Answers

Given:
students going to the game = 56
students in each van = 7
number of vans used = unknown; x

The number sentence that can be used to find out how many vans are needed to take the students to the game is:

7 * x = 56

x = 56/7
x = 8 vans needed.

I had this problem before, 8 vans are needed because 56 students ÷ 7 students / van = 8 vans needed.
