If 124 children sign up for a field trip and each vehicle carries x children, which expression could be used to determine the number of vehicles needed for the trip?

Answer 1

Hello, Nyshae,

There are x children per vehicle.

If x = number of children per vehicle and V = 1 vehicle, we have a relationship that we can use as a conversion factor.

The ratio x/V would allow us calculate how many vehicles we need.

If x = 124 children, we would divide by x/V. = 124 children/(x children/vehicle). The children cancel out and vehicle moves to the top. As an example, if each vehicle holds 12 children:

124 children/(12 children/vehicle) = 10.333 vehicles. We would need to round this up to 11 vehicles, since we con't expect a 0.3333 vehicle to show up.

Answer 2

1 vehicle ⁄ (x children) ×124 children = 124 / x This is your expression to determine no of vehicles
