228 have registered for a sightseeing at the grand canyon. if a tour director can take 35 people on each tour,how many tour directors will be needed to accomadate everyone?

228/35 = 6.51 tour director's needed. Obviously we can't have 0.51 (a part) of a tour director so we will need 7 tour directors to accommodate all 35 people.

Thanks for the help!

To determine how many tour directors will be needed to accommodate everyone, you need to divide the total number of registered participants by the maximum number of people a tour director can take on each tour.

Given that there are 228 registered participants and a tour director can take 35 people on each tour, you can perform the division:

228 registered participants / 35 people per tour = 6.51428571428

Since you cannot have a fraction of a tour director, you will need to round up the number to the nearest whole number because you cannot have a fraction of a tour director.

Therefore, you will need a minimum of 7 tour directors to accommodate everyone (as you can't have a fraction of a tour director).
