📐 Common Percentage Examples
These examples show how percentages work in real situations:
- 20% of 150 = 30
- 75 is what percentage of 300? → 25%
- 40 represents 80% of which number? → 50
- Increase 200 by 15% → 230
- Reduce 100 by 25% → 75
⚖️ Understanding Assignment Weights
Weights determine how much each item affects the final grade:
- Point-Based System: Uses total points earned
- Percentage-Based System: Must add up to 100%
- Equal Weighting: Assign the same value to all tasks
- Mixed Weighting: Higher values have greater influence
⚠️ Mistakes to Avoid
Avoid these common grading errors:
- Mixing point-based and percentage-based weights
- Assigning zero weight to required assignments
- Leaving grade fields empty unintentionally
- Ignoring remaining assessments when planning final grades
