Final answer:
When using 3 eggs, you will need 5 1/6 cups of flour.
Step-by-step explanation:
To find out how much flour you need when using 3 eggs instead of 4, you can set up a proportion. Let x represent the amount of flour needed. The proportion can be set up as follows:
4 eggs / 2 1/3 cups of flour = 3 eggs / x cups of flour
Cross-multiplying, we get:
4 * x = 3 * 2 1/3
Simplifying this equation, we find that x is equal to 5 1/6 cups of flour. So, when using 3 eggs, you will need 5 1/6 cups of flour.
