To solve the problems on the "Customary Weight" worksheet, we need to use the standard conversion rules for weight in the US customary system.
Key Conversion Rules:
*
1 pound (lb) = 16 ounces (oz)
* To go from pounds to ounces, multiply by 16.
* To go from ounces to pounds, divide by 16.
*
1 ton (T) = 2,000 pounds (lbs)
* To go from tons to pounds, multiply by 2,000.
* To go from pounds to tons, divide by 2,000.
Here is the step-by-step solution for each problem on the sheet:
1. 48 oz. = \_\_\_\_\_\_ lb.
* We are converting ounces to pounds, so we divide by 16.
* $48 \div 16 = 3$
* Answer:
3 lb.
2. 3 lb. = \_\_\_\_\_\_ oz.
* We are converting pounds to ounces, so we multiply by 16.
* $3 \times 16 = 48$
* Answer:
48 oz.
3. 1300 lb. = \_\_\_\_\_\_ oz.
* We are converting pounds to ounces, so we multiply by 16.
* $1300 \times 16 = 20,800$
* Answer:
20,800 oz.
4. 2,000 T = \_\_\_\_\_\_ lbs.
* We are converting tons to pounds, so we multiply by 2,000.
* $2,000 \times 2,000 = 4,000,000$
* Answer:
4,000,000 lbs.
5. 16 oz. = \_\_\_\_\_\_ lbs.
* We are converting ounces to pounds, so we divide by 16.
* $16 \div 16 = 1$
* Answer:
1 lb.
6. 32 oz. = \_\_\_\_\_\_ lbs.
* We are converting ounces to pounds, so we divide by 16.
* $32 \div 16 = 2$
* Answer:
2 lbs.
7. 8,000 T = \_\_\_\_\_\_ lbs.
* We are converting tons to pounds, so we multiply by 2,000.
* $8,000 \times 2,000 = 16,000,000$
* Answer:
16,000,000 lbs.
8. 144 lbs. = \_\_\_\_\_\_ oz.
* We are converting pounds to ounces, so we multiply by 16.
* $144 \times 16 = 2,304$
* Answer:
2,304 oz.
Final Answer:
48 oz. =
3 lb.
3 lb. =
48 oz.
1300 lb. =
20,800 oz.
2,000 T =
4,000,000 lbs.
16 oz. =
1 lbs.
32 oz. =
2 lbs.
8,000 T =
16,000,000 lbs.
144 lbs. =
2,304 oz.
