About 7 Maths Chapter 9
In 7 Maths Chapter 9 Rational Numbers, we will learn about the operations regarding Rational Numbers (A rational number is defined as a number that can be expressed in the form p/q , where p and q are integers and q ≠ 0. For example 2. 3/1/ 1/2, -1/2, 0, etc.). By multiplying the numerator and denominator of a rational number by the same non zero integer, we obtain another rational number equivalent to the given rational number. This is the way for obtaining equivalent fractions. Similarly, after simplification, if two rational numbers are equal then these are equivalent rational numbers. Rational number may be positive or negative depending upon the sign of it. In this chapter we will learn to represent the rational numbers on number line. We should write the answers of each question after simplification in standard form.
- A rational number is said to be in the standard form if its denominator is a positive integer and the numerator and denominator have no common factor other than 1.
- To reduce the rational number to its standard form, we divide its numerator and denominator by their HCF ignoring the negative sign, if any.
- There are unlimited number of rational numbers between any two rational numbers.
