Divide both the numerator and the denominator by their greatest common divisor, and the fraction is in lowest terms. The browser-based fraction calculator reduces any fraction for you and also shows its decimal value, all locally with nothing uploaded.
A fraction is in lowest terms when the numerator and denominator share no common factor other than one. To get there, find the greatest common divisor of the top and bottom and divide both by it. For example, 8/12 has a GCD of 4, so dividing gives 2/3, which cannot be reduced further. The value of the fraction does not change; only the way it is written does.
The fraction calculator reduces the fraction to lowest terms automatically and also gives its decimal equivalent, so you can see both forms at once. It can add, subtract, multiply or divide fractions too, always returning the answer reduced. Everything runs in your browser, so nothing you type is uploaded.
It means writing the same value with the smallest whole-number numerator and denominator, by dividing both by their greatest common divisor.
No. Simplifying only changes how the fraction is written; the value stays the same.
