The recipe for the fruit punch is for 8 people.
The number of students wishing to be served fruit punch is 28.
HOW MANY TIMES BIGGER IS 28 THAN 8?
WHAT IS THE RATIO OF StudentsToBeServed to StudentForTheRecipe?
Answer: 28%2F8 and this fraction is reducible.

Use this ratio to compute how much of the concentrate and of the water to use.
