What to Focus On
- Unitary method means finding the value of one first.
- It is used in real-life situations like shopping, travel, and work.
- There are two types: direct and inverse changes.
- Direct variation: more items → more cost or work
- Always divide first, then multiply
- Used in cost, distance, production problems
- Inverse variation: more people → less time
- Multiply first to find one person's time, then divide
- Used in work and time problems
Common Mistakes to Avoid
In direct variation, more items increase cost, but in inverse situations (e.g., more workers, less time) we divide.
The unitary method applies to any proportional situation, including time, distance, work, food, speed, etc.
We must first find the value of one unit before applying the operation.
