Ratio (P5) Practice
Master simplifying ratios, finding unknown quantities using the unitary method, and solving real-world ratio word problems. Ratio is the backbone of P6 problem solving — build it strong here.
Common Mistakes to Avoid
Not simplifying the ratio to its lowest terms
Confusing the part-part ratio with the part-whole fraction
Losing track of which 'unit' represents which quantity
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.
The ratio of red to blue marbles is 3:5. There are 40 marbles altogether. How many red marbles are there?
Simplify the ratio 24:36:60 to its lowest terms.
Ali and Ben share $200 in the ratio 3:2. How much more money does Ali have than Ben?
Parent & Tutor Insight
Ratio is one of the most conceptually rich topics in primary math. When your child is stuck, encourage them to draw a model showing the ratio units — even a quick sketch dramatically reduces errors.
