If a mail-piece weighs 3.4 ounces, what would be the total weight of 5000 pieces in pounds?

To determine the total weight of 5000 pieces of mail, each weighing 3.4 ounces, the calculation begins with converting the weight from ounces to pounds, as there are 16 ounces in a pound.

First, we find the weight of one piece in pounds:

3.4 ounces is equivalent to 3.4 divided by 16, which results in 0.2125 pounds per piece.

Next, to calculate the total weight for 5000 pieces, multiply the weight of one piece by 5000:

0.2125 pounds/piece × 5000 pieces = 1062.5 pounds.

Thus, the total weight of 5000 pieces of mail each weighing 3.4 ounces is 1062.5 pounds. This confirms that the correct answer is indeed 1062.50 pounds.

Understanding the conversion from ounces to pounds and applying multiplication is key in making this calculation, highlighting the importance of handling units appropriately in weight-related questions.
