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
