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.

13 divide by 4= 3r1

each girl gets 3 marbles and 1 will be left over
