Answer: 1 lbs 12 oz
Explanation:
First and foremost, we should note that 16 ounces = 1 pound
Sue has 4lbs 6oz of apples. This in ounces will be:
= (4 × 16) + 6
= 64 + 6
= 70 ounces
Her younger brothers ate some and now she has 2lbs and 10oz. The ounces of apples left will be:
= (2 × 16) + 10
= 32 + 10
= 42 ounces
Therefore, the amount they ate will be:
= 70 ounces - 42 ounces
= 28 ounces
Since 16 ounces = 1 pounds
= 1 pounds 12 ounces
= 1 lbs 12 oz
