Final answer:
To adjust a pancake recipe for different batch sizes, maintain the ingredient ratios. For 9 cups of mix, multiply the number of eggs and milk by 4.5, resulting in 4.5 eggs and 2.25 cups of milk.
Step-by-step explanation:
The question requires mathematical calculations to adjust ingredient measurements for different sizes of batches. If a pancake recipe calls for 2 cups of pancake mix, 1 egg, and 1/2 cup of milk to make one batch, we can write this in a formula representing the relationship between ingredients:
- 2 cups pancake mix → 1 egg → 1/2 cups milk
When wanting to use 9 cups of pancake mix, we need to maintain the same ratio, which is 4.5 times the original recipe. Therefore, we multiply the other ingredients by 4.5, resulting in 4.5 eggs and 2.25 cups of milk needed.
Choosing appropriate units of measurement for different situations is important, such as using liters to measure large liquid volumes or kilometers for longer distances.
