If all of the 12 girls and 18 boys are participating, then the greatest number of teams possible is 6. This is because 12 and 18 are both divisible by 6
There will be 2 girls and 3 boys on every team.
We can double check our numbers:
6 teams of 2 girls = 12 girls
6 teams of 3 boys = 18 boys
This means all the children are accounted for.
I hope that helps!
