Proportion Question Generator
Builds a sheet of proportion questions at the level you ask for. Best-value questions never come out level, and inverse-proportion questions always divide exactly, so no question has two right answers or a fractional one. Every question is computed and checked directly — not a fabricated or AI-guessed fact.
What this generator does
Generates direct and inverse proportion questions with answers. Including both matters: students who have only met direct proportion will happily answer an inverse question by scaling in the wrong direction, and the wrong answer is entirely plausible.
How to use this tool
- Choose a level and how many questions you want.
- Press make questions and work through the sheet.
- Show the answers to mark it, or show the working to see the value of one item or one part.
- Enter a seed word to rebuild the same sheet later.
Common use cases
- Proportion practice at home or school
- Quick maths warm-ups
- Self-testing before a maths quiz
Randomness and fairness
Quantities are drawn with the browser's cryptographic random number generator, constrained so that the scaling factor works out exactly. A seed word rebuilds the same sheet later; it is for reproducibility, not cryptographic strength, so a seeded sheet is deterministic rather than unpredictable.

Common mistakes
- Scaling an inverse relationship as if it were direct
- If four people take six hours, eight people take three, not twelve. Ask whether more of one thing means more or less of the other before doing any arithmetic.
- Assuming everything scales
- Many real quantities are not proportional at all. A question is only a proportion question if the relationship genuinely is one.
