In these problems you will have either groups of an item or one item being a some multiple of times larger than another item. The problem will give you the number of groups or the number of multiples. Also carefully look for where the problem talks about the size of one group or multiple and the total value of all groups or multiples combined as both those part are needed in your answer.
