I would call that 4 average servings, as part of a meat and 3 veg meal
That is 4.25 servings
28 ounces is about 56 tablespoons.
a serving of meat is 4 to 6 ounces. 16 four ounces servings
1 cup and 7 1/2 ounces. That is 1/2 ounce short of two cups. Be careful that you are converting fluid ounces to cups. I tried to figure out how many 1/2 cup servings were in a 15.5 ounce can of beans. Unfortunately the 15.5 ounces is by weight, and the 1/2 cup is by volume. In this case, the servings were also listed as 130g. So, to find the number of servings I divided 15.5 ounces (weight) by 130g to get 3.4 servings.
Assuming the glasses are both 8 ounces, then there would be 2 servings in that.
10 to 15 servings
Since 16 ounces is a pound, there are 50 servings of 16 ounces in a 50 pound bag of peanuts.
16 ounces of green beans would be four 1/2 cup servings.
There are 160 two-ounce servings in 20 pounds. One pound = 16 ounces in weight (avoirdupois) 16 divided by 2 is 8 servings per pound, and 20 x 8 = 160.
16 1 oz. servings or 2 8 oz. servings or 4 4oz. servings
A half gallon has 64 fluid ounces total, so to divide it into 4-ounce servings, you would divide 64/4. So there are 16 servings
