Answer:
54 oz. OR 3 3/8 lbs.
Step-by-step explanation:
1) Convert pounds to ounces. There are 16 ounces in a pound. 20 * 16 = 320.
2) Add the remaining 4 ounces. 320 + 4 = 324.
3) Divide 324 by 6. 324/6 = 54.
Final answer: 54 ounces.
NOTE: If you want the answer in pounds, divide 54 by 16. 54/16 = 3 3/8
Final answer b: 3 3/8 pounds
