Answer=25

explanation

part/whole = %/100 so

10/ whole = 40/100

to get 10 to 40 you multiply by 4 the you have to do the same to the bottom but since we don’t have a whole we have to divide 100 by 4 which = 25. Hope this helps!!!

Fiesta28 [93]

Answer:

17 tour guides

Step-by-step explanation:

First, we need to divide 83 by 5.

  • 83 ÷ 5 = 16 R 3

As you can see, there are 16 tour guides that can handle 5 students each. However, there are a remainder of 3 students, so we need one extra tour guide. Thus, the answer is 17 tour guides.
