Ellie is making a batch of pancakes

and her recipe calls for 1 1/2 cups of
flour and 1 1/4 cups of milk. If she only
has 1 cup of milk, how much flour
should she use to make the same
pancake recipe?

Final answer:

To maintain the proportion of ingredients in her pancake recipe, Ellie should use 1.2 cups of flour with her 1 cup of milk. A proportion is set up using the original amounts and solved to determine the new amount of flour needed.

Step-by-step explanation:

To figure out how much flour Ellie should use with 1 cup of milk instead of 1 1/4 cups, we set up a proportion because the ingredients must be scaled down equally to maintain the correct consistency and flavor of the pancakes. We start with the original ratio of flour to milk, which is 1 1/2 cups of flour to 1 1/4 cups of milk.

Set up the proportion as follows:

Original amount of milk: 1 1/4 cups

Original amount of flour: 1 1/2 cups

New amount of milk: 1 cup

New amount of flour: x cups

Create the equation using the cross-multiplication method:

(1 1/2) / (1 1/4) = x / 1

After solving this equation, you'll find:

(1.5) / (1.25) = x

Now x = (1.5) * (4/5)

x = 1.2 cups of flour

Therefore, Ellie should use 1.2 cups of flour with 1 cup of milk to keep the pancake batter proportions consistent.
