**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?
