Frequently asked questions
How do you add fractions?
Find a common denominator (the bottom numbers must match), then add the numerators. Simplify the result if possible.
What does 'simplified' mean?
A fraction is simplified when the numerator and denominator have no common factors other than 1. We divide both by their greatest common divisor (GCD).
Can I use mixed numbers?
Currently this calculator works with proper and improper fractions. Convert mixed numbers to improper fractions first (e.g., 1½ = 3/2) before entering.
What if the denominator is negative?
A negative denominator is moved to the numerator. Our result always shows the sign in the numerator or as a whole number prefix.
Perform arithmetic operations on fractions — addition, subtraction, multiplication, and division. Results are automatically simplified to lowest terms and shown as both a fraction and a decimal.
