Answer: 5 pounds
Step-by-step explanation: "Oz" is the abbreviation for ounces and "lb" is the abbreviation for pounds.
To convert 72 ounces into pounds, first find the conversion factor for ounces and pounds.
Conversion factor ⇒ 16 ounces = 1 pound
Next, notice that we are going from a smaller unit "ounces" to a larger unit "pounds" and when we go from a smaller unit to a larger unit we divide.
So here, we will divide 72 ounces by the conversion factor which is 16.
72 ÷ 16 = 5
Therefore, 72 ounces = 5 pounds.
