Hello I need help on this problem:

Question

The directions for lemonade say to put 2 cups of the, liquid concentrate into 1 gallon of water. If I want to make 1 pint of lemonade, how many fluid ounces should I use.

Answer 1

how many cups in a gallon?
16

so
2 cups concentrate + 16 cups water = 18 cups lemonade
so
concentrate / lemonade = 2/18 = 1/9

now
how many ounces in a pint (a pint is a pound the world around :)
16

so
1/9 =x/16
x = 16/9 = 1.78 oz
