Answer: 8 girls
Step-by-step explanation:
The team is split into groups that have the same ratio as the whole team.
This means that every group must obey this ratio:
12 girls : 18 boys
At the lowest form (dividing both sides by 6), the ratio is:
2 : 3
Every group must therefore be in a ratio of; 2 : 3.
In a team group that has 12 boys, the number of girls is:
2 : 3
x : 12
3x = 24
x = 24 / 3
x = 8 girls
