The badminton team consists of 11 boys and 7 girls. What is the ratio of girls to ALL team members

To find the ratio of girls to all team members, we need to add the number of boys to the number of girls.

Number of girls: 7
Number of boys: 11

Total number of team members: 11 (boys) + 7 (girls) = 18

Ratio of girls to all team members: 7:18

So, the ratio of girls to all team members is 7:18.
