To make 6 glasses of lemonade, Karla uses 1/2 cup of sugar, 1/2 cup of lemon juice, and 5 1/2 cups of water. If Karla wants to make 10 glasses of lemonade, which proportion can she use to determine how many cups of water, \( w \), she will need?

6 glasses...........1/2.................1/2................51/2 10 glasses.........x.....................y...................z
x=(10*1/2)/6 x=10/2/6 x=5/6 sugar
y=x=5/6 lemon juice
z=(51/2*10)/6 z=(510/2)/6 z=255/6 water

Karla will need approximately 9 1/6 cups of water to make 10 glasses of lemonade. This was calculated using a proportion based on the recipe for 6 glasses. The process involved setting up a ratio and cross-multiplying to solve for the unknown amount of water needed.
