Final answer:
The percentage of fat in the ground beef is 20%.
Step-by-step explanation:
To find the percentage of fat in the ground beef, we need to divide the weight of the fat by the total weight of the ground beef and multiply by 100. In this case, the weight of the fat is 2 pounds and the total weight of the ground beef is 10 pounds. So, the percentage of fat can be calculated as:
Percentage of fat = (Weight of fat ÷ Total weight of ground beef) × 100
Percentage of fat = (2 ÷ 10) × 100
Percentage of fat = 0.2 × 100 = 20%
