Difficulty: MediumUS Customary Weight Measurements

A scrap metal recycling facility is preparing four different compacted bales of aluminum for transport. Arrange the following bales in order from the lightest to the heaviest weight.

  1. 1A bale weighing 38,40038,400 ounces
  2. 2A bale weighing 2,4502,450 pounds
  3. 3A bale weighing 1.251.25 tons
  4. 4A bale weighing 11 ton and 600600 pounds

Answer

The correct order from lightest to heaviest is: the 38,40038,400-ounce bale, the 2,4502,450-pound bale, the 1.251.25-ton bale, and the 11-ton and 600600-pound bale.
By converting all weights to a single common unit (pounds), we find the sequence is 2,4002,400 lbs, 2,4502,450 lbs, 2,5002,500 lbs, and 2,6002,600 lbs. This establishes the correct order from lightest to heaviest.

Step-by-Step Solution

1
Convert the weight of the 38,40038,400-ounce bale to pounds.
38,400÷16=2,40038,400 \div 16 = 2,400 pounds.
Since there are 1616 ounces in a pound, dividing the total ounces by 1616 converts the weight to pounds, providing a common unit for comparison.
2
Evaluate the weight of the second bale.
The weight is already provided in pounds: 2,4502,450 pounds.
No conversion is necessary for this item.
3
Convert the weight of the 1.251.25-ton bale to pounds.
1.25×2,000=2,5001.25 \times 2,000 = 2,500 pounds.
Since there are 2,0002,000 pounds in a US short ton, multiplying the ton value by 2,0002,000 gives the weight in pounds.
4
Convert the weight of the mixed-unit bale (11 ton and 600600 pounds) to pounds.
1×2,000=2,0001 \times 2,000 = 2,000 pounds. Adding the extra 600600 pounds results in 2,000+600=2,6002,000 + 600 = 2,600 pounds.
Convert the ton portion to pounds first, then add the remaining pounds to find the total.
5
Compare all four weights in pounds and sequence them from lightest to heaviest.
2,4002,400 lbs << 2,4502,450 lbs << 2,5002,500 lbs << 2,6002,600 lbs.
Ordering the standardized numerical values determines the correct sequence of the items.

Key Concept

Converting between ounces, pounds, and US short tons to compare varying weights.
