Question

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?

Answer 1

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

Answer 2

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 !!
