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 Fractions True Fractions: Fractions with numerator less than denominator are called true fractions. 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 fraction .3 reduction and general fraction.
Turning a fraction into equal parts with smaller numerator and denominator is called reduction. A fraction whose numerator and denominator are prime numbers is called simplest fraction.
Divide the scores of different denominators by the scores of the same denominator equal to the original score, which is called comprehensive score.
