The directions for lemonade say to put 2 cups of the liquid concentrate into 1 gallon of water. If Olivia only wants to make 1 pint of lemonade, how many fluid ounces of concentrate should she use? Explain.
a gallon is 16 cups
so, the concentrate is 2/18 = 1/9 of the total volume.
so, what is 1/9 of 16 fl oz?
Thank you Steve.
sure. Sometimes you have to clear away the words and just ask
what have I been told?
What do I already know about the subject?
What do they want to know?

To find out how many fluid ounces of concentrate Olivia should use to make 1 pint of lemonade, we need to first determine the ratio of concentrate to water provided in the recipe.
The recipe states that for 2 cups of concentrate, we need 1 gallon of water. Since there are 16 cups in a gallon, the ratio becomes:
2 cups concentrate : 16 cups water
To find the proportionate amount of concentrate for 1 pint (which is equal to 2 cups), we can set up a proportion:
2 cups concentrate / 16 cups water = x cups concentrate / 2 cups water
By cross-multiplying, we get:
(2 cups concentrate) * (2 cups water) = (16 cups water) * (x cups concentrate)
4 cups concentrate = 32 cups concentrate
Therefore, Olivia should use 4 cups (or 32 fluid ounces) of concentrate to make 1 pint (or 16 fluid ounces) of lemonade.
To put it simply, since the recipe calls for 2 cups of concentrate for 1 gallon of water, and Olivia only wants to make 1 pint of lemonade (which is equivalent to 2 cups), she should use 4 cups (or 32 fluid ounces) of concentrate.
