there are 1000 students on a track team. 18/10 do running events. 22/8 do throwing events. Of the students who are in the track team how many do throwing and running combined? how do you know? show your work using as many methods as possible.
Hmm..did you mean to say 10/18 and 8/22 ?
Because 18/10 means that out of ten students, eighteen of them do running.
