In a school, the ratio of soccer players to volleyball players is 4 : 1. The number of soccer players is how many times the numb
soldier1979 [14.2K]

Your question appears to be phrased incorrectly.  If the ratio of soccer players to football players is 4:1 then for every 1 football player there are 4 soccer players.  For example, if there are 3 football players, there would be 12 soccer players.

The equivalent expression would be   S = 4F

The statement: "there are 4 more soccer players than football players" is not the same thing.  It simply means that we add 4 to the total of football players to find out how many soccer players there are.

The equivalent expression would be   S = F + 4

That being said:  An equivalent ratio to 4:1  would be  8:2 ,  12:3,  16:4, ...

Think of the ratio as a fraction.  4:1 = 4/1

4/1 = 8/2 = 12/3 = 16/4 ..., etc.
