Question

During his lunch hour, Matt asked 24 students how many after-school activities they participated in. This list shows the survey results.

Answer 1

`Ratio = 1 : 6`

Explanation:

Given

`n = 24`

Results:

`1, 2, 0, 0, 3, 2, 4, 2, 1, 4, 3, 2`

`1, 1, 2, 1, 0, 3, 3, 2, 4, 1, 1, 0`

Required

Ratio of students not participating to all students

Students not participating are represented with 0;

So, we have:

`n(0)= 4`

The ratio is then calculated as:

`Ratio = n(0) : n`

`Ratio = 4 : 24`

Divide by 4

`Ratio = 1 : 6`
