Final answer:
Coach Matt cannot make 8 teams with the same number of fifth and sixth graders on each team, but he can make 4 teams.
Step-by-step explanation:
To determine if Coach Matt can make 8 teams using all the fifth and sixth graders, we need to find the greatest common factor (GCF) of 16 and 36. The GCF is the largest number that divides both 16 and 36 evenly. In this case, the GCF is 4. Therefore, it is not possible for Coach Matt to make 8 teams with the same number of fifth graders and sixth graders on each team. However, Coach Matt can make 4 teams with 4 fifth graders and 4 sixth graders on each team.
