Answer:
a. Dance
Explanation:
We will find the ratios' common denominators and compare them
Dance: 2/3 girls to boys ratio
soccer: 3/5 girls to boys
Chess: 8/15 girls to boys
Lets find a common factor
all of the denominators (bottom numbers evenly go into 15)
2/3=10/15
3/5=9/15
8/15= 8/15 because it already has 15 as a denominator
The number with the greatest numerator is gonna be our answer;
10/15 or 2/3
