Nadia Sent Two Boxes In The Mail The First Box Had A Weight Of 5 Pounds 4 Ounces The Second Box Had A Weight Of 2 Pounds 6 Ounces What Is The Difference Between The Weights Of The Two Boxes In Pounds And Ounces?
Introduction
In everyday life, we often encounter situations where we need to compare weights of objects, especially when it comes to shipping and packaging. In this article, we will explore how to calculate the difference between the weights of two boxes, each with a unique weight measurement in pounds and ounces.
Weight Measurements
Before we dive into the calculation, let's understand the weight measurements of the two boxes.
- The first box has a weight of 5 pounds 4 ounces.
- The second box has a weight of 2 pounds 6 ounces.
Converting Weight Measurements to a Common Unit
To calculate the difference between the weights of the two boxes, we need to convert both measurements to a common unit. In this case, we will convert both measurements to ounces.
- 1 pound is equal to 16 ounces.
- The first box has a weight of 5 pounds 4 ounces, which is equivalent to (5 x 16) + 4 = 80 + 4 = 84 ounces.
- The second box has a weight of 2 pounds 6 ounces, which is equivalent to (2 x 16) + 6 = 32 + 6 = 38 ounces.
Calculating the Difference in Weight
Now that we have both measurements in ounces, we can calculate the difference in weight.
- Difference in weight = Weight of the first box - Weight of the second box
- Difference in weight = 84 ounces - 38 ounces
- Difference in weight = 46 ounces
Converting the Difference to Pounds and Ounces
Since we want to express the difference in weight in pounds and ounces, we need to convert the difference from ounces to pounds and ounces.
- 1 pound is equal to 16 ounces.
- 46 ounces is equal to 2 pounds and 14 ounces (46 ÷ 16 = 2 with a remainder of 14).
Conclusion
In conclusion, the difference between the weights of the two boxes is 2 pounds 14 ounces. This calculation demonstrates the importance of converting weight measurements to a common unit before comparing them.
