Fraction reduction calculator

When the numerator and denominator of a fraction are divided by a common factor at the same time, the value of the fraction remains unchanged. This process is called reduction. The basis for reduction is: the basic properties of fractions.

For example, a/b is a fraction. A can be written as c*d and b can be written as c*e. Then a/b can be written as d/e, because there is a common factor c that can reduce the numerator and denominator at the same time.

The simplest fraction: A fraction whose numerator and denominator have no common factors except 1 is called the simplest fraction.

Note: When reducing fractions, try to use mental arithmetic. Reducing a fraction to a fraction that is equal to it but has a smaller numerator and denominator is called reduction. When reducing fractions, use the common factor of the numerator and denominator (except 1) to divide the numerator and denominator of the fraction; usually divide until the simplest fraction is obtained.

When reducing fractions, if you can quickly see the greatest common factor of the numerator and denominator, it is easier to directly use their greatest common factor to divide.
