Percentage (P5) Practice
Find percentages of quantities, express one number as a percentage of another, and solve percentage increase/decrease and discount problems. A direct bridge to P6 percentage, GST, and profit/loss questions.
Common Mistakes to Avoid
Dividing by the NEW value instead of the ORIGINAL value when finding percentage change
Confusing 'percentage of a quantity' with 'one number as a % of another'
Not checking whether the answer makes sense (e.g. percentage > 100%)
Practice Questions
Try each question. When you're stuck, reveal the Socratic strategy — a guided hint that teaches you how to think, not just what to write.
40% of a class of 30 students are girls. How many boys are in the class?
A jacket originally priced at $120 is sold at a 25% discount. What is the selling price?
In a school, there are 240 boys and 160 girls. What percentage of the students are girls?
Parent & Tutor Insight
Percentage is the most-tested topic across P5 and P6. When your child practises, always ask them to state the 'base' (i.e. what is the percentage OF?). This one habit eliminates the most common class of errors.
