A recipe uses 1 lb. of ground beef to make 8 meatballs. How much ground beef is required to make 4 meatballs?

The correct answer is determined by understanding the proportion of ground beef used per meatball. In this scenario, if 1 pound of ground beef yields 8 meatballs, we can find the amount of beef needed for each individual meatball by dividing the total beef by the number of meatballs.

1 pound equals 16 ounces, so when you divide 16 ounces by 8 meatballs, you find that each meatball requires 2 ounces of ground beef. To calculate how much beef is needed for 4 meatballs, you would multiply the amount needed for one meatball by 4:

2 ounces × 4 meatballs = 8 ounces.

Therefore, to make 4 meatballs, 8 ounces of ground beef is necessary, making the correct answer 8 oz.
