Final answer:
The question involves calculating food consumption percentages for different flocks and then using those percentages to estimate flock sizes. It requires division and multiplication to determine how many birds of a total of 30 are in each flock, based on the food they consumed out of a total of 300 pieces.
Step-by-step explanation:
The question appears to involve calculating percentages from given values and then applying those percentages to a different total. Specifically, we'll divide the number of pieces of food eaten by each flock by the total amount of 300 pieces, resulting in decimal forms that can then be converted to percentages. These percentages represent how much of the total food each flock consumed. Afterwards, we will multiply each food percentage by the total number of birds, which is given as 30, to determine the number of birds in each flock, based on the amount of food they consumed.
To give an example similar to what's required in the question, for a hypothetical flock that ate 88 pieces of food: (88 / 300) × 100 would give us the food percentage for that flock, and then this percentage can be multiplied by 30 to estimate the flock size or number of birds. The actual question's data points will differ, but this provides a model for the calculation process.
