GCSE Maths Ratio Mistakes
Ratio questions can look simple but often become tricky when they involve sharing, totals, differences or units.
Common Ratio Mistakes
- Using one part instead of the total number of parts
- Misreading the order of the ratio
- Forgetting to simplify the final ratio
- Confusing ratio with fractions or percentages
Exam tip: Add the ratio parts when the question gives the total amount.
Common mistake: In the ratio 2:3, there are 5 total parts, not 3.
