Question

Alison made 21/2 glasses of fruity iced tea for 7 her friends. Considering that each friend drank an equal quantity, how many glasses were served per person

Answer 1

You could convert 21/2 to a whole number by multiplying it by 2 and then dividing by 2, so 21/2 = 21/2 = 10.5, then dividing the total by the number of people that is 10.5 / 7 = 1.5 glasses/person.
