The number or algebraic expression written below the fractional line in a fraction is called the denominator. Fractions with known denominator are called algebraic expressions, and fractions with unknown denominator are called fractions. Denominator cannot be zero.
Fraction (from Latin, "broken") stands for a part of the whole, or more generally, any equal number of parts. In daily spoken English, scores describe parts of a certain size, such as one-half, five-eighths and three-quarters. Molecules and denominators are also used for uncommon fractions, including compound fractions, complex fractions and mixed numbers.
In a complex fraction, the longest dividing line is called the main dividing line of the complex fraction. No matter how many numbers or operations are above and below the main fractional line, they are used as the numerator and denominator of the complex fractional line respectively.
Features: Denominator represents the value of a population, and numerator represents the value occupying the population. In fractions, the number or algebraic expression written below the fractional line is called denominator, which means dividing the unit 1 into several parts on average. Fractions with known denominator are called algebraic expressions, and fractions with unknown denominator are called fractions.
The importance of learn mathematics:
1. Mathematics is closely related to our life. To say that the real effect of learning mathematics is not reflected in exam-oriented education, but in my own thinking about the future.
2. The importance of mathematics is self-evident. Mathematics is the foundation of all sciences and an important channel to cultivate logical thinking. It can be said that every major progress of our mankind is strongly supported by mathematics.
3. The application of mathematical knowledge in life is everywhere. From the calculation of daily living costs, to astronomy, geography, quality control, agricultural economy, aerospace, there are shadows of using mathematics.
