Which of the measures below represents 3 tons and 12 pounds converted to pounds?
A. 3,012 lb
B. 6,012 lb
C. 9,012 lb
D. 12,012 lb
The correct answer and explanation is:
To convert 3 tons and 12 pounds to pounds, follow these steps:
- Understand the conversion factor:
- 1 ton is equivalent to 2,000 pounds.
- Convert 3 tons to pounds:
- 3 tons × 2,000 pounds/ton = 6,000 pounds.
- Add the 12 pounds:
- 6,000 pounds + 12 pounds = 6,012 pounds.
Thus, the correct answer is B. 6,012 lb.
Explanation:
When performing unit conversions, it’s important to know the relationship between the units you’re converting. In this case, we are converting tons to pounds, which involves using the conversion factor of 2,000 pounds per ton.
The given problem has both tons and pounds as the units of measurement. By first converting the tons to pounds, we are able to then add the extra pounds to get the total weight in pounds. This ensures that we account for all the weight accurately and in the correct units.
If the problem only involved pounds and no tons, the answer would simply be the sum of the given pounds. However, because the problem involves both tons and pounds, we had to take the extra step of converting the tons first before adding the pounds.
In summary, the proper procedure is:
- Convert tons to pounds.
- Add the remaining pounds to the total.
The correct final result is 6,012 pounds.
