"Common Fractions of Fractions" PPT Courseware 2
communication and discovery
Do you remember what the common factor of a fraction is?
According to the basic properties of fractions, fractions with different denominators can be converted into fractions with the same denominator. This process is called the common denominator of fractions.
Similarly, according to the basic properties of fractions, fractions with different denominators can be converted into fractions with the same denominator. This process is called the common fraction of a fraction.
For example, to divide 1/x and 1/x-3, first find their common denominator which is x(x-3)
Can you divide the fractions -3/2x2 and a/3x?
Because there are many common denominators, 6x2 is the simplest one, which is called the simplest common denominator.
The basis for common scores is: the basic properties of fractions
The key to common denominators is to find the simplest common denominator
Simplest common denominator:
product
1. The least common multiple of the coefficients
2. The highest power of the same letter
