Answer :
Answer:
a 1lb 13 oz
Step-by-step explanation:
1 lb= 16 oz. convert to oz. 68oz - 39oz = 29 oz. vconvert back to lbs.= 1 lb 13 oz.
Final answer:
To perform subtraction with measurements, it's important to align units correctly. In the given scenario, we borrowed 1 lb (equal to 16 oz) from the pounds column to subtract the ounces. Consequently, we subtracted the pounds, after accounting for the borrowed pound. Thus, 4 lbs 4 oz minus 2 lbs 7 oz equals 1 lb 13 oz.
Explanation:
The problem presented belongs to the mathematics subject, specifically subtraction of weights measured in pounds (lb) and ounces (oz). To solve this, let's consider the subtraction of regular numbers. Just like with addition, it's necessary to align the units correctly when performing subtraction of measurements.
First, let's tackle ounces. Subtract 7 oz from 4 oz. Since 7 is larger than 4, we can't do that directly. Hence, we borrow 1 lb (which is equal to 16 oz) from the pounds column. Now, it becomes 20 oz - 7 oz, resulting to 13 oz.
Next, let's subtract pounds. We originally had 4 lbs, but we borrowed 1 lb for the ounces column earlier. So, we subtract 2 from the remaining 3 lbs, which leaves us with 1 lb.
So, 4 lbs 4 oz minus 2 lbs 7 oz equals 1 lb 13 oz. Hence, the answer is (A) 1 lb 13 oz.
