How to use the Fraction Calculator
The Fraction Calculator adds, subtracts, multiplies, or divides two fractions, then reduces the result by dividing the numerator and denominator by their greatest common divisor.
What this tool is useful for
- Add and subtract fractions using a common denominator.
- Multiply or divide fractions and simplify the result.
- Convert the resulting fraction to a decimal.
Practical example
One half plus one quarter uses a common denominator of four: 2/4 + 1/4 = 3/4. For division, multiply the first fraction by the reciprocal of the second.
Helpful tips
- A denominator cannot be zero.
- Division by a zero-valued fraction is undefined.
- Use the least common denominator when working by hand, although any valid common denominator produces the same simplified answer.
