How much does a single piece weigh if a bundle of 250 pieces weighs 6.4125 pounds?

To determine the weight of a single piece in a bundle of 250 pieces that weighs 6.4125 pounds, the total weight of the bundle is divided by the number of pieces in that bundle.

First, perform the calculation:

6.4125 pounds (total weight) divided by 250 pieces equals the weight of one piece.

Calculating this gives:

6.4125 ÷ 250 = 0.02565 pounds.

When rounded to four decimal places, this matches closest to the value presented in the answer choice for the piece's weight. The choice of 0.0257 pounds is essentially a rounded figure derived from the calculated weight.

This process illustrates how division helps in understanding the distribution of total weight across individual items, thus applying a practical aspect of mathematical operations in real-world contexts like shipping and handling of mail.
