Explanation:
2 cans to be equally shared by 5, that means everybody gets 2/5 of a can of paint.
5 boxes of crayons shared by 2 friends, so each gets 5/2 boxes.
2 packages of paper for 5 children, so each gets 2/5 of a package.
5 balls of yarn for 2 sisters, so each gets 5/2 balls.
for such questions it is always : how much is there in total divided by how many parts are needed.
that gives you how much of the total goes to every part.
