Frequently asked questions

How do you simplify a fraction?
Divide the numerator and denominator by their greatest common divisor (GCD). For example, 6/8 has a GCD of 2, so it simplifies to 3/4. This calculator simplifies every result automatically.
What's the difference between a proper, improper, and mixed fraction?
A proper fraction's numerator is smaller than its denominator (3/4). An improper fraction's numerator is equal to or larger (7/4). A mixed number combines a whole number and a proper fraction (1 3/4) — the same value as 7/4, written differently.
