Question

.

Marian has a custard recipe that requires 1 cup of sugar, 6 eggs, 3 cups of milk, and 1 teaspoon of vanilla. But she has only 4 eggs. She decides to adjust the recipe to the 4 eggs. How much milk will she need?

Answer 1

So 4 eggs is 2/3of 6 eggs, so to get the amount of milk we multiply the 3 cups by 2/3 (or just divide by 3 and multiply by 2) and get 2 cups of milk.
Hope this helps!
