💡 Exam Tips: Reverse Percentages
- Identify what the given amount represents - is it after an increase or decrease?
- Calculate the percentage the final amount represents of the original
- Use division - divide the final amount by the multiplier
- Always check your answer by working forwards
- Look for key phrases: "after", "including", "final amount", "reduced to"
- Be careful with direction - decrease means final < 100%, increase means final > 100%
- Show your working - state what percentage the final amount represents
