Question

how would i solve something like 15/3?

Answer 1

That is 15/3 which is 3 into 15 and your answer is 5

Answer 2

The division operator is a way of sharing objects into groups of the same size. A way of thinking of the problem is, "How many times can 3 repeat itself before reaching 15?". 
1 Time = 3
2 Times = 6
3 Times = 9
4 Times = 12
5 Times = 15 
Awesome! That means that five 3's can go into 15. So, 15/3 = 5. The more you practice, the easier it will get!
