It takes 18 times the ingredients in the recipe to make 18 servings.
Explanation:
Since I have a recipe for cheese quesdillas that makes 5 servings, and I want to make enough for 90 servings, to determine what is the conversion factor that will determine how many times the ingredients of the recipe are needed, the following calculation must be performed:
90/5 = 18
Therefore, it takes 18 times the ingredients in the recipe to make 18 servings.
