In this lesson, we will learn what is a proportion, how to solve proportions, and how to solve application problems using proportions.
We can find unknown quantities when we know similar ratios for comparison, using proportions. We find proportions often in word problems, for example those involving baking ingredients, and in comparing similar figures in Geometry. We can represent an unknown quantity in a proportion with a variable, and then solve it using one-step, two-step, or multi-step equation methods.
