1 significance of the score
Divide the unit "1" into several parts on average, and the number representing such a part or parts is called a fraction.
In the score, the middle horizontal line is called the dividing line; The number below the fractional line is called the denominator, indicating how many copies the unit "1" is divided into on average; The number below the fractional line is called the numerator, indicating how many copies there are.
Divide the unit "1" into several parts on average, and the number representing one part is called fractional unit.
2 Classification of scores
True fraction: The fraction with numerator less than denominator is called true fraction. The true score is less than 1.
False fraction: Fractions with numerator greater than denominator or numerator equal to denominator are called false fractions. False score is greater than or equal to 1.
With fraction: False fraction can be written as a number consisting of integer and true fraction, which is usually called with fraction.
3 Reduction and comprehensive score
Changing a fraction into a fraction equal to it, but with smaller numerator and denominator, is called divisor.
The denominator of a molecule is a fraction of a prime number, which is called simplest fraction.
Dividing the scores of different denominators by the scores of the same denominator equals the original score, which is called the total score.
