Macy, Kayley, Maddie, and Rachel collected 13 marbles. They want to share the marbles equally. How many marbles will each of the 4 girls get? How many marbles will be left over?
Each of the 4 girls will get 3 marbles with 1 left over. If 4 girls get 3 marbles each, that is 4 times 3. This is 12. Now since there are 13 marbles, we know that there is 2 left over because 13-12 is 1.
