Melinda has 1 seashell, and Jun has 9 seashells. If Melinda and Jun put their seashells together and then divide them up equally, how many will each one of them have?
5 seashells, because 9 + 1 = 10 and if you were to give them an equally amount of seashells it would be 5 if you split 10 in half. Therefore the answer would be 5.
