Anonymous users2024-02-06Reduction means that the numerator and denominator can be divided by the same number to get a simplified fraction.
The steps are as follows:
1.decompose the numerator and denominator into factors;
2.Find the common factor of the numerator and denominator;
3.Eliminate the non-zero common factor.
If you can quickly see the greatest common factor of the numerator and denominator, it is easier to remove them directly by their greatest common divisor.
The numerator and denominator of the fraction are divided by the same number at the same time (except 0), and the magnitude of the fraction remains unchanged - the basic properties of fractions".
Method 1: It can be removed by the common factor of the numerator and denominator (except 1).
Examples" >> >, then".
It's the simplest fraction.
In this way, a fraction that is equal to it, but whose numerator and denominator are smaller, is called a fraction (usually the simplest fraction).
Method 2: Directly remove the numerator of the fraction and the greatest common factor of the denominator (except 1).
Examples" >> >, then".
It's the simplest fraction.
Summary: Generally, the numerator and denominator of fractions are removed by the common factors of the numerator and denominator (except 1), usually until the simplest fraction.

Anonymous users2024-02-04If the denominator is a multiple of the numerator, use the numerator to reduce the fraction; If the denominator is not a multiple of the numerator, the greatest common factor is used to reduce the fraction;

Anonymous users2024-02-03Significance: Turning a fraction into a fraction that is equal to it, but the numerator and denominator are relatively small, is called a fraction.
Simplest fraction: The fraction whose numerator and denominator are coprime numbers is called the simplest fraction.
Note: When reducing the fraction, try to use oral calculation, and generally use the common divisor of the numerator and denominator (except 1) to remove the numerator and denominator of the fraction; It is usually divided until the simplest score is obtained.
If you can quickly see the greatest common divisor of the numerator and denominator, it is easier to remove them directly by their greatest common divisor.

Diaper usage is as follows:
1. Diapers are commonly used daily necessities for babies, dry diapers can keep babies sleeping all night, and are commonly known as "diapers" due to strong water absorption. Among them, superabsorbent resin (referred to as polymer SAP) is an excellent material for making baby diapers, which is made of starch and acrylic as the main raw materials; The outstanding feature is the surprisingly large amount of water absorption and storage. >>>More
