Please could someone help by explaining and giving the answer.. just cannot get my old head round this one to aid my daughter..
James plays football for his school team. He scores a goal (S) every third match (M) he plays. Which equation represents this information?
S=M
S=3M
M=S-3
S=1/3M
S=M-3

S=1/3M
Scores every 3rd match, so after 3 matches 1 goal, after 6 matches 2 goals etc..

not so easy to see it like that - if written s=m/3 it is clearer. I suppose what they mean is s=(1/3)*m

Thank you both so much.
If you have the time would you kindly explain what S=3M would mean in comparison.
cheers

s=3m would mean 3 goals per match
ie 3 matches = 9 goals
