Main Learning Objective:
Understand how to solve proportions by finding cross products and using the Identity Property of Multiplication to isolate variables.
Key Takeaways:
- A proportion is defined as two equal ratios.
- Cross multiplying two equal ratios a/b = c/d yields the equivalent cross products equation ad = bc.
- Variables can be located in either the numerator or denominator of a proportion.
- Isolating the variable involves dividing both sides of the equation by the coefficient, utilizing the Identity Property of Multiplication.
