Frequently asked questions
How do you add fractions with different denominators?
Find the least common denominator (LCD), convert both fractions, then add numerators. The calculator does this automatically.
Can I enter mixed numbers?
Yes. Enter whole number and fraction parts separately, or as a single mixed number like 2 3/4.
Are results always simplified?
Yes. The GCF reduces the result to lowest terms — 4/8 becomes 1/2.
What about dividing by zero?
A zero denominator is invalid. The calculator shows an error if you enter 0 in the denominator.
Is this fraction calculator free?
Yes. Unlimited operations with no signup.
