Best ResponseYou've already chosen the best response.1so in this case number of staff is proportion to number of student by a ratio of 1:15 so 1 is proportion to 15 as if what is proportion to what? remember number of staff i let it to be x and number of student is given to be 120 so 1:15

Best ResponseYou've already chosen the best response.0x/120=1/15, we get x=8 (teachers) now, 42*3coaches=126 but student+teachers, i.e, 120+8=128

Best ResponseYou've already chosen the best response.1it is essentially saying if there are 15 student then 1 staff is taking care of them, now there are 120 students, how many staff is needed to take care of those 120 students?

Best ResponseYou've already chosen the best response.0So this is wat I did 1+15=16 120/16=7.5=8 1x8=8(for staff) + 15x8=120(for students) =128 now for coaches 42x3=126 so its not enough they need 2 more seats
