If Karla can make 6 glasses of lemonade with 0.5 cup of sugar, 0.5 cup of lemon juice, and 5.5 cups of water, then the proportion is:
6:0.5:0.5:5.5
To make it simpler, we multiply 10 to both sides so that there will be no decimal places anymore and becomes like this:
60:5:5:55
If you want to get the number of cups that you will use for sugar, lemon juice, and water if you want to make 10 glasses of lemonade, just cross multiply and you will get:
a.) 8 1/3 cup of sugar
b.) 8 1/3 cup of lemon juice
c.) 9 1/6 cup of water
Answer: 60 : 5 : 5 : 55
