Question:  Ella’s summer drama camp has a 5 to 7 ratio of boys to girls. If there are a total of 84 students in her camp, how many girls are there?

Answer:   49 girls

Solution:   We can set up a proportion to solve this. A ratio of 5 boys to 7 girls also means there are 7 girls for every 12 students. 7 girls/ 12 students = x girls/ 84 students. Solving this we find there are 49 girls signed up for summer drama camp.
