To determine if the student is correct, we need to compare the actual ratio of purple buttons to green buttons. The actual ratio can be found by dividing the number of purple buttons (4) by the number of green buttons (3), which equals 4/3.
The student wrote the ratio as 3:4, which is the inverse of the actual ratio. Therefore, the student is incorrect.
The correct ratio of purple buttons to green buttons is 4:3.
