Answer:
14 hamburgers
Explanation:
The problem uses division, but we can create a proportion to see how the division works.
Since we know that Chelsea can make 1 hamburger with 0.16 pounds and allow x to represent the number of burgers Chelsea can make with 2.24 lbs of meat, we have:


As the proportion shows, we can divide 2.24 by 0.16 to get x = 14.
Check: 0.16 lbs * 14 patties = 2.24 lbs
