School guidelines require that there must be at least 2 chaperones for every 25 students going on a school trip. how many chaperones must there be for 8 students?

25 students got 2 chaperones
so 1 will get 2/25

and thus 8 will get 2/25×8 = 0.64 chaperone

but is it possible?? No chaperone can not be in decimal so at least 1 is required !!

And thus 8 will get 2/25×8 = 0.64 chaperone
