195 students.

Explanation:

Each group of three created (or used) 9 pictures.

So that means three pictures per student.

585/3 = 195 students.

Answer 2

585 / 9 to get the number of groups = 65

then you take 65 x 3 for number of students in each group and you get the final answer of 195 students
