Tina had 33 glasses and Kate had 56 how many they had each

I think you would add all the glasses together which you would then get 89 then you would divide that number by two because we are looking for how much glasses Tina and Kate could both get so 89/2 = 44.5 so they would each evenly get 44.5 glasses. I'm sorry I think this is what you were looking for?
