I don't think I really understand the question but I tried to simplify the equations
Answer:
Part 1)
or 
Part 2)
or 
Step-by-step explanation:
Write the ratio as a fraction in simplest form
Part 1) 15 girls to 6 boys
we know that
To find out the ratio, divide the number of girls by the number of boys
so

Simplify
Divide by 3 both numerator and denominator

Part 2) 24 plays for 3 teams
we know that
To find out the ratio, divide the number of plays by the number of teams
