A recipe for fruit salad includes
cup of grapes for 4 servings.
How many cups of grapes are needed for 30 servings of this fruit salad?
To find out how many cups of grapes are needed for 30 servings of this fruit salad, we can set up a proportion using the given information.
We are told that for 4 servings, it requires 1 cup of grapes. Let's represent this information as a ratio:
4 servings / 1 cup of grapes
To find out how many cups of grapes are needed for 30 servings, we'll set up another ratio using the information given:
30 servings / x cups of grapes
Now, we can set up a proportion by equating the two ratios:
4 servings / 1 cup of grapes = 30 servings / x cups of grapes
To solve this proportion, we can cross-multiply:
4 * x cups of grapes = 1 * 30 servings
Simplifying the equation, we have:
4x = 30
To isolate x (the number of cups of grapes needed for 30 servings), we'll divide both sides of the equation by 4:
x = 30 / 4
x = 7.5
Therefore, for 30 servings of this fruit salad, you will need 7.5 cups of grapes.
