Justin has 20 pencils,25 erasers,and 40 paper clips.He organizes them into groups with the same number of items in each group.How many items can he put in each group?
You could add all those numbers together and get 85. Then divide that by 5 and your remainder is 17. He can put 17 items in each group (or if you do 85 divided by 17 Justin can put 5 items in each group).
