Learning Objective
I can use proportional reasoning to solve scaling problems in real-world contexts.
- 1
When solving proportions using relationships, you can use multiplication or division to find the unknown value.
- 2
When using cross multiplication to solve proportions, you must first cross multiply, then set the cross products equal to each other, and then solve.
- 3
When solving proportions using relationships, you can look for a relationship that uses multiplication or division horizontally, from side to side between the ratios.
