Final answer:
To measure ingredient amounts with only the two measuring cup sizes of 1/3 and 1/4, you can use equations or other models.
Step-by-step explanation:
To measure ingredient amounts with only the two measuring cup sizes of 1/3 and 1/4, we can use equations or other models. Let's say we have a recipe that requires 2 cups of flour and 3 cups of milk. We can use the 1/3 measuring cup to measure the flour by filling it 6 times (2 cups x 1/3 cup = 6 fills) and the 1/4 measuring cup to measure the milk by filling it 12 times (3 cups x 1/4 cup = 12 fills). This way, we can measure the required amounts using the given measuring cup sizes.
