FAQs on RS Aggarwal Solutions Class 7 Chapter - 4 Rational Numbers (Exercise 4B) Exercise 4.2: Download Free PDF

1. Define what is a rational number and mention its standard form mentioned in Class 7 chapter 4 of RS Aggarwal?

A rational number is a subtype of a real number, which can be expressed in p/q form where “p” is not equal to 0. A fraction that does not have zero as a denominator is a rational number. For example,  \[\frac{1}{4},\frac{1}{5},etc..,\frac{1}{0}, \frac{2}{0}\] , etc are not rational numbers as anything divided by zero is infinite and can not be determined. In a rational number, numerator and denominators are integers and the denominator is not zero. When the rational number is divided, it results in a decimal form which can be recurring or non - recurring. The standard form of a rational number is when there are no common factors between the numerator and denominator except the number one. For example, 12/15 could be simplified to the standard form of ⅘.

2. What are positive and negative rational numbers mentioned in Class 7 chapter 4 of RS Aggarwal?

A rational number is a subtype of a real number, which can be expressed in p/q form where “p” is not equal to 0. A fraction that does not have zero as a denominator is a rational number. For example,  \[\frac{1}{4},\frac{1}{5},etc..,\frac{1}{0}, \frac{2}{0}\] , etc are not rational numbers as anything divided by zero is infinite and can not be determined. In a positive rational number, both p and q are positive numbers and in a negative rational number, either p or q is a negative number. In a rational number, numerator and denominators are integers and the denominator is not zero. 

3. How can RS Aggarwal help Class 7 students?

RS Aggarwal has been recommended by experts, teachers, and toppers to students preparing for the CBSE maths exam. It is in perfect match with the CBSE syllabus, curriculum, and exam pattern. By practicing these exercises, students could easily solve the problems in their final exams. Students are supposed to answer them by themselves and cross-check them with the solutions provided.

4. What are the properties of rational numbers?

A rational number is a subtype of a real number, which can be expressed in p/q form where “p” is not equal to 0. A fraction that does not have zero as a denominator is a rational number. For example,  \[\frac{1}{4},\frac{1}{5},etc..,\frac{1}{0}, \frac{2}{0}\] , etc are not rational numbers as anything divided by zero is infinite and can not be determined. 


When we add or subtract any two rational numbers, the result is also a rational number.

A rational number does not change if we multiply, divide the numerator and denominator with the same number

5. What are rational numbers and how are they different from irrational numbers?

A rational number is a subtype of a real number, which can be expressed in p/q form where “p” is not equal to 0. A fraction that does not have zero as a denominator is a rational number. For example,  \[\frac{1}{4},\frac{1}{5},etc..,\frac{1}{0}, \frac{2}{0}\] , etc are not rational numbers as anything divided by zero is infinite and can not be determined. On the other hand, irrational numbers are also a type of real numbers but they can not be represented in a simple fraction format. It can not be written in a fraction format like p/q where p and q are integers and q is not equal to zero. Any real number which is not a rational number is irrational.
