Mathematical Properties in Shipping Rate Calculations

During an onboarding session for inventory managers at a logistics firm, a supervisor presents a formula for adjusting the volume capacity of standard shipping crates. The combined adjustment factor is calculated as: 715823157\frac{7}{15} \cdot \frac{8}{23} \cdot \frac{15}{7} Rather than performing tedious multi-digit multiplication, the supervisor notes that this expression can be simplified in seconds by recalling core mathematical definitions and rules.

As a training exercise, write a brief explanation recalling and defining the specific mathematical definitions and properties that allow this product to be simplified. Your response must:

  1. State the name of the mathematical property that allows you to change the order of the factors to group the reciprocals adjacent to each other: 715157823\frac{7}{15} \cdot \frac{15}{7} \cdot \frac{8}{23}.
  2. Define what a reciprocal is, and state the result when a fraction is multiplied by its reciprocal (such as 715157\frac{7}{15} \cdot \frac{15}{7}).
  3. State the name of the mathematical property that allows you to simplify the remaining expression after multiplying the reciprocals, yielding the final answer of 823\frac{8}{23}.
