Frequently Asked Questions
How do I practice simplifying fractions?
Use this tool to get randomly generated fractions. Simplify each one to its lowest terms by dividing numerator and denominator by their GCD, then type your answer and click Check.
What does "lowest terms" mean?
A fraction is in lowest terms (simplest form) when the numerator and denominator share no common factor other than 1. For example, 2/3 is in lowest terms, but 4/6 is not — it simplifies to 2/3.
How do I know if my fraction answer is correct?
Your answer is correct if it is equivalent to the fully simplified form. The tool accepts any equivalent simplified form and shows the correct answer immediately after you check.
What is the difference between Easy, Medium, and Hard difficulty?
Easy uses small numbers (up to 8), Medium uses numbers up to 15, and Hard uses numbers up to 25 with more complex GCDs. All difficulties generate fractions that require simplification.
