The amount of club soda is 2 times the amount of white grape juice, which is expressed as a ratio of 2:1.
The student question is about determining the ratio of the amounts of two ingredients in a fruit punch recipe: club soda and white grape juice. To find the ratio, we compare the amount of club soda to the amount of white grape juice.
The amount of club soda is given as 4 cups, and the amount of white grape juice is given as 2 cups. To find how many times the amount of club soda is to the amount of white grape juice, we divide the quantity of club soda by the quantity of white grape juice.
4 cups of club soda ÷ 2 cups of white grape juice = 2.
Therefore, the amount of club soda is 2 times the amount of white grape juice. To express this as a ratio, we write it as club soda: white grape juice = 2:1.
The value of the ratio is 2.
