Answer:

#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#
