In this lesson, you will learn how to solve word problems using proportions. The instructor shows examples of setting up proportions to keep ingredients in recipes in proportion to maintain the taste, and how to set up ratios to determine how much of an ingredient is needed in a recipe when the number of servings changes. By using cross-products and solving equations, you can easily find the amount of an ingredient needed for a recipe.
