Simplifying Fractions Worksheets

Reduce fractions to lowest terms

Simplifying fractions — writing them in their lowest terms — is essential for comparing, adding, and understanding fractions. This generator builds worksheets of fractions that share a common factor, and the student rewrites each in its simplest form. You set the difficulty by capping the largest denominator, and an answer key is generated automatically.

How simplifying works

To simplify a fraction, divide the numerator and denominator by their highest common factor. For example, 6/8 has an HCF of 2, so it reduces to 3/4. A fraction is in lowest terms when the only number that divides both top and bottom is 1. Spotting the HCF quickly is the key skill this worksheet builds.

What you can customise

• Largest denominator — smaller for easy fractions, larger for harder ones.
• Problems per sheet — a quick set or a full page.
• Answer key, Name & Date — for marking and classroom use.

How to use it

1. Set the largest denominator to control difficulty.
2. Choose how many problems you want.
3. Toggle the answer key and Name/Date fields.
4. Preview the live PDF, press Generate New for a fresh set, then download or print.

Teaching ideas

Encourage pupils to find the HCF in one step rather than dividing by small factors repeatedly. Link to equivalent fractions — simplifying is the reverse of scaling up. For a challenge, raise the largest denominator so fractions need larger common factors to reduce.
