Final answer:
To get a recipe exactly right, one must calculate the total amount of ingredients needed by multiplying the quantity required per batch by the number of batches. Then, use proportions or conversion factors to find out the amount needed of other ingredients or to convert between measurement units.
Step-by-step explanation:
Understanding Recipe Proportions
The question is related to determining the correct proportions when scaling recipes. First, you need to calculate the total number of cups required based on the number of batches and cups per batch. For instance, if making 5 batches that each require 3 cups, then the total needed would be 3x5=15 cups. After determining the total amount needed, you set up a proportion to find out how much of another ingredient is needed in relation to the given quantity.
For example, if the proportion is 4 cups to 1 quart, and you need 15 cups, the equation would be 4 cups/1 quart = 15 cups/x quarts.
Another situation might require converting tablespoons to cups. If Henrietta needs 7 tablespoons of Romano cheese per salad and is preparing 8 salads, she would need a total of 56 tablespoons. To convert tablespoons to cups, you would divide by the conversion factor, which in this case is 16 tablespoons per cup. Therefore, 56 divided by 16 would give you the number of cups required.
