Question

How many teams of at least 5 students and at most 7 students can be chosen from 15 students?​

Answer 1

3

Explanation:

least students= 5

maximum students = 7

total number of students = 15

no: of grps if 5 students per grp = 15/5 = 3

no: of grps if 7 students per grp = 15/7 = 2.14 ~ 2

However, if they ask us how many teams in final we can say 3 as it is the maximum number of groups that can be formed b a grp of 15 students ... if we make 7 students per grp... one would be left out .

Answer 2

5 Students = 3 Teams

7 Students = 2 Teams

To find out the answer we can use the following equation

`(Total)/(Students) \\\\(15)/(5) = 3 \\(15)/(7) = 2.14... \\`

If you run into a decimal number, like we did when we had a team of 7, you can just round down!
