Introduction to Recipe.

Here are diagrams representing three mixtures of powdered drink mix and water.

1. How would the taste of Mixture A compare to the taste of Mixture B?

2. Complete the following statement:

(a). Mixture B uses ______ cups of water and ______ teaspoons of drink mix.

(b). The ratio of cups of water to teaspoons of drink mix in Mixture B is ________.

(c). Mixture C uses ______ cups of water and ______ teaspoons of drink mix.

(d). The ratio of cups of water to teaspoons of drink mix in Mixture C is ________.

(e). How would the taste of Mixture B compare to the taste of Mixture C?

3. A recipe for one batch of cookies calls for 5 cups of flour and 2 teaspoons of vanilla.

(a). On the applet below, use the Pen tool to draw a diagram that shows the amount of flour and vanilla needed for two batches of cookies.

(b). How many batches can you make with 15 cups of flour and 6 teaspoons of vanilla?

(c). How much flour and vanilla would you need for 5 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?
