there are 65 students out of 125 students who play on an athletic team. what is the ratio of students who do not play on an athletic team to all of the students

There are a total of 125 students, 65 of whom play on an athletic team, and (125-65), or 60, who do not.

The ratio of students who do not play on an athl. team to all of the students i thus 60/125, or 12/25, or 0.48.

Ok so you subtract 65 from 125 to get the kids who AREN'T in any athletic team (60). SO then you get 60:125, or 12:25 simplified
