1 pound = 16 ounces
If a serving is 1/4 of a pound, that means a serving is 4 ounces because 16/4 = 4.
So, with 15/16 pounds, you will get 3.75 servings per bag. This is because there will be 4 servings per bag, but only if there is an even 16 ounce bag. So, like I said before, 16/4 = 4. If you count it out, you get an even 4 ounces 3 times and 3 ounces once, which gives you 3 3/4 (3.75) servings.
I hope I was able to help. Best of luck!
