miss handson ask students to prepare booths for the Fall Fair. In all, 40 students volunteered. miss Hanson wanted no more than six students in a group. if one teacher helps each group, how many teachers will be needed?

That's 6 groups of 6 and 1 group of 4, so 7 teachers.
Nothing was said about having the largest groups possible. Suppose only 3 students are in each group. That will require 14 teachers.
If a "group" is to imply at least 2 students, then that means as many as 20 teachers might be required.
Poorly posed problem. 
40/6 = 6 2/3
Round to nearest whole teacher.
