To make lemonade, kate uses 1 cup of lemon juice and 2 cups sugar. if she makes a larger amount of lemonade with 10 cups of sugar, how many cups of lemon juice does she need?

If we put this in to ratio, it would be, lemon juice to sugar, 1:2. Therefore, to get from 2 to 10 you multiply by 5, so if you multiply 1 by 5 you get your answer as 5 cups of lemon juice. Hope this helps!

What are the options
