1. I have a recipe for cookies that uses 3 parts chocolate chips to 2 parts white chocolate. If I use 9 ounces of white chocolate to make my cookies how many ounces of chocolate chips should I use?

To find out how many ounces of chocolate chips you should use, you can set up a ratio based on the parts given in your recipe. Since the ratio of chocolate chips to white chocolate is 3:2, if you're using 9 ounces of white chocolate (which is 2 parts), you can set it up like this: \( 3 parts \text{ chocolate chips} / 2 parts \text{ white chocolate} = x \text{ ounces of chocolate chips} / 9 \text{ ounces of white chocolate} \). By cross-multiplying, you find that \( x = 3 \times (9/2) \), which equals 13.5 ounces. So, you'll need 13.5 ounces of chocolate chips to keep the delicious balance! Understanding ratios isn’t just helpful in the kitchen; it can aid in various real-life situations! For instance, if you ever find yourself in a situation where you need to mix different types of paint or create a signature drink, applying ratios can help you achieve the perfect blend. Master this nifty skill, and you’ll look like a pro wherever you go!
