A recipe calls for 1 cup of milk for every 2½ cups of flour to make a cake that would feed 6 persons. How many cups of both flour and milk will be needed to make a similar cake for 8 people?
4 2/3 cups
Total cups (flour + milk) for 6 persons = 1 + 2.5 = 3.5 cups. For 8 persons = (8/6) × 3.5 = 28/6 = 4 2/3 cups.
