We have mentioned some of the important points to be remembered from Class 7 Maths chapter 9 to help you perform well in the exams.

- Every integer is a rational number, but a rational number need not be an integer.
- Two rational numbers are equal if they have the same standard form.
- To convert a rational number to an equivalent rational number, multiply or divide both its numerator and denominator by a non-zero integer.
- If there are two rational numbers with a common denominator, then one with the larger numerator is larger than the other.
- A positive rational number is greater than zero.
- Every negative rational number is less than zero.
- Rational numbers can be represented on the number line.

**Ans:** In Chapter 9, students will be introduced to the concept of rational numbers along with their addition, subtraction, multiplication and division operations.

**Ans:** By multiplying the numerator and denominator of a rational number by the same non zero integers, we obtain another rational number equivalent to the given rational number. This is how we obtain equivalent fractions.

**Ans:** 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.

**Ans:** The main topics of Class 7 Maths Chapter 9 are as follows:

– Need For Rational Numbers

– What Are Rational Numbers

– Positive And Negative Rational Numbers

– Rationals Numbers On a Number Line

– Rational Numbers in Standard Form

– Comparison of Rational Numbers

– Rational Numbers Between Two Rational Numbers

– Operations On Rational Numbers

– Addition

– Subtraction

– Multiplication.

– Division

**Ans:** The word ‘rational’ is derived from the word ‘ratio’. Any number that can be expressed as a ratio is a rational number. Mathematically, a rational number is defined as a number which can be expressed in the form of p/q where p and q are integers and q ≠ 0.
