Percentage Question Generator

Builds a sheet of percentage-of-a-number questions where the amount is chosen so the answer always comes out whole, and the working shows the find-ten-per-cent-and-scale method rather than a formula.

How many questions

Between 1 and 30. Ten fills a page.

Level

Seed (optional)

A word reproduces the same sheet, so a whole class can be given the identical set.

Gentle uses 10%, 20%, 25%, 50% and 75%. Stretch uses percentages with no easy shortcut.

Paper size

Print size

Margin

Millimetres of blank edge, 5 to 40.

How to print this, or save it as a PDF

There is no PDF to download, and there does not need to be. Open the print command in your browser and choose “Save as PDF” as the destination. The page addresses and dates a browser normally prints across the top and bottom are already kept off.
Set the scale to 100%, not “fit to page”. This sheet is already the exact size of the paper you chose, so anything that resizes it makes every measurement on it wrong.
Leave the paper size in the dialog set to the same one you chose here.

Your questions will appear here.

What this generator does

The amounts are chosen to make the answer whole, because an unconstrained draw gives results like 37.845 most of the time — which quietly turns a percentage exercise into a decimal-arithmetic exercise and tests the wrong thing. The level controls how far the percentages stray from the ones with an easy shortcut.

How to use this tool

Choose how many questions you want and how awkward the percentages should be.
Press make questions, and work through the sheet.
Show the answers to mark it, or show the working to see the scaling method.
Enter a seed word to rebuild the same sheet later.

Understanding the controls

How many questions: One to thirty. Fifteen is about right for mental work, where the aim is speed rather than a written method.
Level: Gentle stays with 10%, 20%, 25%, 50% and 75%, all of which have a shortcut. Standard widens the set; stretch uses percentages such as 7%, 17% and 95% where the shortcut has to be built rather than recalled.
Seed: A word rebuilds the identical sheet, so a repeat run can be timed against the first without new questions confusing the comparison.
Show the answers / show the working: The working finds one per cent first and scales up, which is the method that works mentally and generalises to every percentage on the sheet.

Common use cases

Percentage practice at home or school
Mental-maths work on scaling from ten per cent
Quick maths warm-ups
Self-testing before a maths quiz

How this generator works

The percentage is drawn first, then the amount is drawn as a multiple of whatever makes that percentage come out whole — for 7% that is a multiple of a hundred, for 25% a multiple of four. The check multiplies rather than divides: the printed answer times a hundred must equal the amount times the percentage, so no step of the verification can round.

Randomness and fairness

The percentage and the amount are not drawn independently — the amount's step size follows from the percentage, which is the constraint that keeps every answer whole. Within that constraint the amount is a free draw.

For how randomness is produced across the whole site, see how Generate Random works.

Limitations and good to know

Only percentage of an amount is produced. Finding the original after a rise or fall runs the calculation the other way, and is set on its own sheet.
Answers are always whole numbers, which is deliberate for practice and unlike most real percentage calculations.
Seeded sheets repeat exactly, which makes the seeded path deterministic, not cryptographic randomness.

Practical tips

Ask for the ten per cent first and build from it. Finding 10% and scaling is the method that works mentally, and it is what makes 5%, 15% and 20% instant.
A stretch sheet is worth doing slowly. The point is not speed but noticing that 17% is 10% + 5% + 2%.
