Ellie's favorite recipe requires 3 eggs and makes 6 servings. Grace modifies the recipe by using 7 eggs and increasing all other
grandymaker [24]

The modified recipe will make 14 servings.

Step-by-step explanation:

Given,

Eggs used = 3

Servings made = 6

Ratio of eggs to servings = 3:6

Eggs used in modified recipes = 7

Let,

x be the number of servings = x

Ratio of eggs to servings = 7:x

Using proportion;

Eggs to servings :: Eggs to servings

3:6::7:x

Product of mean = Product of extreme

6*7=3*x\\42=3x\\3x=42

Dividing both sides by 3

\frac{3x}{3}=\frac{42}{3}\\x=14

The modified recipe will make 14 servings.
