Q2. What are rational numbers according to Chapter 9 Rational Numbers of Class 7 Maths?

**Ans:** Rational numbers can be expressed as numbers that are in the ratio of x and y. Here x (numerator) and y (denominator) are positive integers and y is not equal to 0. X and y should not have any common divisors other than 1. There are positive and negative rational numbers. Positive rational numbers are those whose numerator as well as denominator are positive integers, whereas negative rational numbers have either the numerator or denominator number as negative.

Q3. How can we obtain rational numbers between two rational numbers according to Chapter 9 Rational Numbers of Class 7 Maths?

**Ans:** Rational numbers refer to numbers that don’t have 0 as the denominator, and where both the denominator and the numerator are integers. To obtain rational numbers between two rational numbers we can simplify it by dividing it by 2. For example; the rational number between 3/2 and 4/2 is 7/4 as 3/2+4/2=7/2.

We can perform all the operations such as add, subtract, multiple and divide with rational numbers. Rational numbers can perform operations only with other rational numbers and will not be able to with irrational numbers.

Q4. What are the Important Topics Covered in NCERT Solutions of Chapter 9 Rational Numbers of Class 7 Maths?

**Ans:** NCERT Solutions for Class 7 Maths Chapter 9 is one of the most important chapters in Mathematics. There are many important concepts and topics that are covered in this chapter from the examination point of view. The important topics covered are Introduction to rational numbers, need for rational numbers, what are rational numbers, positive and negative rational numbers, rational numbers on the number line, In the standard form of rational numbers, operations on rational numbers (addition, subtraction, multiplication and division) and obtaining rational numbers between two rational numbers.

Q5. How do you represent rational numbers in their standard form as explained in Chapter 9 Rational Numbers of Class 7 Maths?

**Ans:** Rational numbers are a part of the real number system. Rational numbers are represented in terms of a fraction in their standard form. Rational numbers are represented in the ratio of x and y. Here x (numerator) and y (denominator) are positive integers and y is not equal to 0. Rational numbers are used to represent almost everything. For example; taxes are done in decimals, division of pizza or anything. These numbers are fractions and hence rational numbers.
