a pronumeral is essentially the same as a variable. A letter can stand for something that is unknown and either changing or not. If changing it is called a variable or pronumeral. If not changing, it is called a constant.
 
As for the rest of your question, "explain how to choose pro numerals for various quantities of food in the one question" you'll need to give more info or write it more clearly, probably both.
Perhaps a try: b = the number of ounces of broccoli needed for a particular dish for 10 people when a particular recipe is designed for 4 people.
 
Does that help?
