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?
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.
To adjust the recipe for pound cake since Gavin only has 5 eggs instead of the required 7 eggs, you will need to calculate the ratio of eggs to flour in the original recipe.
The ratio of eggs to flour in the original recipe is 7 eggs to 3 cups of flour.
To find out how many cups of flour Gavin should use, we can set up a proportion using the given information:
(5 eggs) / (7 eggs) = (x cups of flour) / (3 cups of flour)
Cross-multiplying the proportion:
5 * 3 = 7 * x
15 = 7x
Dividing both sides of the equation by 7:
15 / 7 = x
x ≈ 2.14
So, Gavin should use approximately 2.14 cups of all-purpose flour.
