Okay. You have 20 oz of egg noodles.
You need 5 oz to make one of chicken noodle soup,
Then I can make 20 / 5 = 4 services
For 4.5 lb,
I6 ounces = 1 pound.
4. 5 x 16 ounces = 4.5 lb= 72 ounces
Then, we have 8 oz per serving.
Then we can have 72/8 = 9 services.
4.5 x 16 / 8 = 72/8 =9 servings
Okay. 2 tbsp = 1 serving
18 tbsp = (18 x 1) / 2 = 9 servings
