A recipe for pound cake calls for 7 eggs and 3 cups of all-purpose flour. Gavin only has 5 eggs. How many cups of all-purpose flour should he use?

Answer 1

To find out how many cups of all-purpose flour Gavin should use, we need to determine the ratio of eggs to flour in the original recipe.

The ratio is 7 eggs to 3 cups of all-purpose flour.

Using this ratio, we can set up a proportion to solve for the missing amount of flour:

7 eggs / 3 cups of flour = 5 eggs / x cups of flour

Cross-multiplying, we get:

7x = 5 * 3

Simplifying, we have:

7x = 15

Dividing both sides by 7, we find:

x = 15 / 7 = 2.14 (rounded to the nearest hundredth)

So, Gavin should use approximately 2.14 cups of all-purpose flour.
