Answer:
18 cups of dried split peas. 16 quarts of water. 6 cups of chopped onions. 8 cups chopped celery. 16 pounds ham shank.
Step-by-step explanation:
Since that is a recipe for 8 people and 8 is a factor of 32, we can multiply the ingredient amounts by 4 (4 x 8 is 32).
2 1/4 c x 8 = 18 c.
2 qt x 8 = 16 qt.
3/4 c x 8 = 6 c.
1 c x 8 = 8 c.
2 lb x 8 = 16 lb.
