100% of the food is all of the food.
To make it easier to work with, lets pick 100 for the number of guests, and 100 for the amount of food.
Since 2% of the guests take 4% of the food, the consumption rate for the 2% of the guests is 4/100, or .04 of the food (combined) or individually, .02 ... (.04 ÷ 2)
Since 98% of the guests take 96 of the food. the consumption rate for the 98% of the guests is 96/100 or .96 of the food (combined) or individually, .00979591 ... (.96 ÷ .98)
