Converting Units of Weight in Real World Problems

This lesson teaches how to solve real-world problems involving weight conversion from larger units to smaller units. It covers common conversions in the customary weight system, such as pounds to ounces and tons to pounds. The lesson addresses common misunderstandings in unit conversion and demonstrates the use of tables to facilitate the process. Two real-world problems are solved: comparing the weights of Leslie and Kathy, and comparing the weights of Pedro's and Julio's dogs. The lesson emphasizes the importance of converting to the same units for accurate comparison.
