Changing Recipe Quantities - In Proportion

This document has 3 pages. Print only the pages you need.

Each of the 3 worksheets lists a recipe with quantities of each ingredient based on a given number of servings. Students are challenged to use what they know about proportionality and multiplying by fractions to calculate quantities for different numbers of servings.

Encourage students to write answers using proper fractions and mixed numbers as opposed to decimals. The quantities for the first ingredient in each worksheet are shown as examples.

Recipes and Proportions (page 1 of 3)

Hint: Notice that the relationship between the different quantity does not change. e.g. no matter how many people are to be served, the number of chicken breasts is also twice the number tablespoons of olive oil and there are always three times more zucchinis than cloves of garlic.

 

You can use this to simplify your calculations e.g. if you calculate the quantity of tablespoons of olive oil, you will be able to find the number of chicken breasts by doubling that number.
