Question

Teachers divided students into groups of 3. Each group of 3 wrote a report that had 9 pictures in it. The students used 585 pictures altogether. How many students were there in all?

Answer 1

Each group used 9 pictures, first divide total pictures by pictures per group to find total groups:

585 / 9 = 65 total groups.

Each group had 3 students.

Multiply total groups by students per group:

65 x 3 = 195 total students

Answer: 195 students.
