Final answer:
To find the amount of salt needed when a recipe is doubled, multiply the original amount of salt by 2.
Step-by-step explanation:
When you are given a recipe that includes the amount of salt as a fraction, you can use that information to find the amount of salt needed when the recipe is doubled. Let's say the original recipe calls for 1/2 teaspoon of salt. To find the amount of salt needed when the recipe is doubled:
- Multiply the original amount of salt by 2 to account for doubling the recipe. In this case, 1/2 teaspoon * 2 = 1 teaspoon.
- Therefore, when the recipe is doubled, you would need 1 teaspoon of salt.
