🎯 Goal
Understand and solve problems involving ratios and proportions.
📖 Lesson Description
- A ratio compares two quantities (e.g., 3:4)
- A proportion states two ratios are equal (e.g., 3/4 = 6/8)
- Cross-multiply to solve proportions
🔎 Examples
- Ratio of 2 apples to 3 oranges = 2:3
- Proportion: 2/3 = x/9 → 2×9 = 3x → x = 6
âœï¸ Practice
- Solve 4/5 = x/20
- Write the ratio of 7 boys to 5 girls
- Check if 6/9 = 8/12 forms a proportion
