Fraction Question Generator

What this generator does

Draws a fraction simplification or addition question with the answer hidden. Addition questions are constructed with denominators chosen to have a workable common multiple, because a pair drawn at random produces denominators like 47 and 53 most of the time — arithmetically valid and useless for practice.

How to use this tool

1. Choose a level and how many questions you want.
2. Press make questions and work through the sheet.
3. Show the answers to mark it, or show the working to see the common denominator each sum uses.
4. Enter a seed word to rebuild the same sheet later.

Common use cases

• Fraction practice at home or school
• Quick maths warm-ups
• Self-testing before a maths quiz

Randomness and fairness

Numerators and denominators are drawn with the browser's cryptographic random number generator, then constrained so that every answer is exact: a fraction of an amount always divides, and a sum is always cancelled down before it is shown. A seed word rebuilds the same sheet later; it is for reproducibility, not cryptographic strength, so a seeded sheet is deterministic rather than unpredictable.

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

Practical tips

• Have students state the common denominator before adding anything. Most fraction errors happen at that step, and they are invisible once the addition is written down.
