Tavon is making two types of drinks, lemonade and lemon-flavored tea. He needs 12 lemons and 3 cups of sugar for each gallon of lemonade but only 3 lemons and 1 cup of sugar for each gallon of tea. If he has a total of 36 lemons and 10 cups of sugar, how much of each type of drink can he make?

First, you will have to convert all of these numbers to decimals.
2/3=0.6 repeating 
25%=0.25
3/5=0.6
0.40 is already in the decimal form
Then, you order them.
25%, 0.40, 3/5, 2/3 (because the 6 is repeating. So basically 0.60 is smaller than 0.66 in case you are wondering)
