Are fractions simplified?

By default, all fractions are automatically simplified to their lowest terms using the greatest common divisor (GCD). You can disable this option.

What range can I use?

You can set the maximum denominator from 2 to 10,000. Numerators are generated to create proper and improper fractions.

What's the difference between proper and improper fractions?

Proper fractions have numerators smaller than denominators (like 3/4). Improper fractions have numerators equal to or larger than denominators (like 5/4).

Can I use this for teaching fractions?

Yes! Perfect for creating fraction worksheets, quizzes, and practice problems. Students can also practice simplifying fractions by disabling auto-simplify.
