Each student gets 4 because 4 times 16 is 64 n after putting up half she gave out 64 so 4 is your answer
There's a bunch of them like if you simplify you could get 3/4.I'll give you some more.
Examples:14/16 21/24 28/32 and 35/40.
My brain was getting tired to think...but there's more.
Hope this helps :D
