Answer: The answer is one will have 8 and one will have 9 so roughly 8
Step-by-step explanation
So to start we need to add all the kids together that are playing
5+12= 17
Now we need to divide the number of kids by the number of teams that there are
17 divided by 2=8.5
So each team will have 8 but one will have nine
Hope this helps :D
