Fraction Calculator FAQ
How do you add fractions?
To add fractions, find a common denominator, convert both fractions to equivalent fractions with that denominator, then add the numerators. For example: 1/2 + 1/3 = 3/6 + 2/6 = 5/6.
What's the difference between proper and improper fractions?
A proper fraction has a numerator smaller than the denominator (like 3/4). An improper fraction has a numerator equal to or larger than the denominator (like 5/4), which can be converted to a mixed number (1 1/4).
How do you multiply fractions?
Multiply fractions by multiplying the numerators together and the denominators together: (a/b) Ă (c/d) = (aĂc)/(bĂd). Then simplify if possible.
How do you divide fractions?
To divide fractions, multiply by the reciprocal of the second fraction: (a/b) á (c/d) = (a/b) Ă (d/c) = (aĂd)/(bĂc).
When to Use This Calculator

Common Mistakes to Avoid
- Adding fractions without finding a common denominator â 1/3 + 1/4 is not 2/7; you must convert to like denominators first.
- Not simplifying the result â always reduce your answer to lowest terms (e.g., 4/8 should be simplified to 1/2).
- Confusing mixed numbers and improper fractions â convert mixed numbers (2½) to improper fractions (5/2) before calculating.
