Question

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?

Answer 1

I'd set up a ration problem

1 cup lemon juice = 2 cups sugar
----------------------- ----------------
x lemon juice 10 cups sugar

2x = 10
x = 5
