About Fraction
Fractions follow four rules, and the calculator shows every step so you can follow along.
Add or subtract: convert both to a common denominator (the lowest common multiple keeps the numbers small), then add or subtract the numerators. 1/4 + 1/6 becomes 3/12 + 2/12 = 5/12.
Multiply: multiply the numerators together and the denominators together.
Divide: flip the second fraction and multiply — dividing by 2/3 is the same as multiplying by 3/2.
Simplify: divide the top and bottom by their greatest common divisor. 18/24 has a GCD of 6, so it becomes 3/4. Results with a numerator bigger than the denominator are also shown as mixed numbers, such as 2 ⅔.
Common questions
- How do I add fractions with different denominators?
- Convert both to a common denominator (the lowest common multiple works best), add the numerators, then simplify. 1/4 + 1/6 becomes 3/12 + 2/12 = 5/12.
- How do I simplify a fraction?
- Divide the numerator and denominator by their greatest common divisor. 18/24 has a GCD of 6, so it simplifies to 3/4.
