How it works
To add or subtract, the fractions are put over a common denominator, then the numerators are combined. To multiply, numerators multiply and denominators multiply. To divide, the first fraction is multiplied by the reciprocal of the second. The result is then reduced by dividing the numerator and denominator by their greatest common divisor.
How to use the Fraction Calculator
Enter the values requested by the tool and start with one realistic example. Read the result together with its unit or label, then change one input at a time if you want to compare options. Keeping a note of the original figures makes the calculation easier to check later.
A result is only as useful as the values and settings entered. Try a simple known example if you want to check your working.
