Question

Kathryn has a recipe that needs teaspoon

of butter for every 2 cups of milk. If Kathryn
increases the amount of milk to 4 cups, how
many teaspoons of butter are needed?

Answer 1

2 teaspoons of butter

We know that the number has increased to 4 cups of milk, which is double the original amount, so we just double the teaspoons of butter needed as well.

Cups of milk:

4

Teaspoons of butter:

2
