In your journal, you chose a healthy recipe. Then you made a plan to scale it up to cook for a large party. You found how many servings the original recipe made. Then you accounted for the number of
guests. You multiplied the original measurements to find the amount of each ingredient you'll need to make one serving for each guest. This involved multiplying fractions.
In your post, describe your cooking plans to your peers. Explain how you multiplied fractions to solve the problem:
• Describe the healthy recipe you chose.
• List the measurement of each ingredient in the original recipe and how many people it serves. List the number of people invited to your party.
Explain how you calculated the amount of each ingredient you'll need to prepare enough servings for all of your guests.
• State the amount of each ingredient you'll need to cook for your party.
• Describe other ways you use fractions to benefit your health in real life. For instance, do you use them for structuring an exercise routine or scheduling daily activities? Name a situation that might require
you to multiply fractions or mixed numbers. Specify whether you would be multiplying a fraction or mixed number by an integer or multiplying two fractions or mixed numbers together.
For my cooking plans, I chose a healthy recipe for a quinoa salad with roasted vegetables and lemon vinaigrette. The original recipe serves 4 people.
The measurements for each ingredient in the original recipe are:
- 1 cup quinoa
- 2 cups vegetables (a mix of bell peppers, zucchini, and red onion)
- 2 tablespoons olive oil
- 1 lemon (juice and zest)
- Salt and pepper to taste
Since I'm planning to cook for a large party, I have 20 guests invited. To calculate the amount of each ingredient I'll need, I will multiply the measurements in the original recipe by 20 (the number of guests). To do this, I'll need to multiply fractions.
To calculate the amount of quinoa needed, I'll multiply 1 cup by 20:
1 cup * 20 = 20 cups of quinoa
To calculate the amount of vegetables needed, I'll multiply 2 cups by 20:
2 cups * 20 = 40 cups of vegetables
For the olive oil, lemon juice, and zest, which are measured in tablespoons, I'll multiply 2 tablespoons by 20:
2 tablespoons * 20 = 40 tablespoons of olive oil, lemon juice, and zest
Finally, I'll season with salt and pepper to taste, so I won't need to multiply these measurements.
Therefore, for my party, I'll need:
- 20 cups of quinoa
- 40 cups of vegetables
- 40 tablespoons of olive oil, lemon juice, and zest
Besides cooking, I also use fractions to benefit my health in real life when measuring and portioning my meals. For example, if a recipe serves 4 people and I only need to cook for myself, I would need to divide the measurements by 4 to have the right amount for one serving. This involves dividing fractions.
Another situation that might require me to multiply fractions is when I'm calculating the nutritional information for a recipe or snack mix that includes different ingredients with varying serving sizes. To find the total nutritional value, I would need to multiply the fraction representing the serving size of each ingredient by the appropriate fraction representing the amount of that ingredient in the recipe.
