A recipe for ONE batch of cookies calls for 5 cups of flour and 2 teaspoons of vanilla. How much flour and vanilla would you need for FIVE batches of cookies? Whether the ratio of cups of flour to teaspoons of vanilla is 5:2, 10:4, or 15:6, the recipes would make cookies that taste the same. We call these EQUIVALENT ratios. Find another ratio of cups of flour to teaspoons of vanilla that is equivalent to these ratios. How many batches can you make using this new ratio of ingredients?
