Question

3 out of 8 students are athletes. If there are 1280 students at the school, how many are not athletes?

Answer 1

`800` students at the school are not athletes.

Explanation:

If 3 out of 8 students are athletes (`3/8xxstudents`), it stands to reason that 5 out of 8 students are not athletes (`5/8xxstudents`).

If we represent the number of students who are not athletes by `x` and we know the total number of students to be `1280`, we can write an equation:

`x=5/8xx1280`

`x=5xx160`

`:.x=800`
