Final answer:
The 72-ounce steak weighs 4.5 pounds when converted from ounces to pounds, which is the necessary unit to find the weight to the nearest tenth of a pound.
Step-by-step explanation:
The weight of the steak in the food challenge is 72 ounces. To find the weight to the nearest tenth of a pound, we need to use the conversion factor that 1 pound is equal to 16 ounces.
We can then divide 72 ounces by 16 ounces per pound to find the weight in pounds.
72 ÷ 16 = 4.5
Therefore, the steak weighs 4.5 pounds when rounded to the nearest tenth of a pound.
Converting from ounces to pounds is useful in various scenarios including labeling packages of steak, as Jeffrey is doing in the butcher shop.
