Question

A recipe for cookies calls for 4 cups of flour, half as much sugar as flour, and half as much butter as sugar. How many cups of butter will you need if you double the recipe?

Answer 1

Answer:

You will need 2 cups of butter.

Step-by-step explanation:

There are 2 ways to figure this out.

#1. If you need 4 cups of flour, then you will need 2 cups of sugar.

If you need 2 cups of sugar, then you will need 1 cup of butter.

Which means that if you double the recipe you will need 2 cups of butter.

#2. If you are doubling the recipe, then you will need 8 cups of flour.

Which means you will need 4 cups of sugar.

And you will need 2 cups of butter!

I hope this helps! :)
