Chapter 1: Rational Numbers, Important Topics for RS Aggarwal Class 8 Solutions

Natural, whole, and integer numbers

You must comprehend the definitions of Natural Numbers, Whole Numbers, and Integers before you can successfully complete the RS Aggarwal tasks for Class 8 Chapter 1. Natural numbers are all positive countable numbers; nevertheless, they do not include zero. Whole numbers are defined as all natural numbers plus zero. Then, zero and all other positive and negative numbers are combined to form an integer.

Rational Numbers

Rational numbers may be stated as the ratio of two integers. For instance, the numbers 1, 2, 1, 3, and 4 are all rational numbers. In this case, 0 cannot be the denominator.

Some students are weak and lack the fundamental understanding of mathematics needed to perform well on exams. Since math is a practical topic, a student can’t benefit from just learning it. In order to excel in this topic and earn the greatest possible grades on the tests, a student must consistently practice it. Similar to this, regularly practicing the RS Aggarwal answers for Class 8 Chapter 1 would aid students in developing the necessary knowledge of rational numbers.

For a better understanding of these exercises, students can consult Chapter 1 of RS Aggarwal Class 8 Solutions. The Utopper website offers students free access to the RS Aggarwal Class 8 Solutions Chapter 1 PDF. Although it is a common misunderstanding among students that geometry, measurements, and trigonometry are the most challenging topics in mathematics, focusing just on these topics is unacceptable.

Another challenging area of mathematics that can easily confuse a learner is the chapter on rational numbers. Therefore, it is imperative to possess a solid understanding of the ideas and formulas relating to rational numbers. These chapter’s solutions will teach students a lot. Here are a few ideas that they will comprehend more fully if they consult the solution file.

What are Rational Numbers: Meaning

Any number that can be written as a quotient or fraction of two integers, either positive or negative, is referred to as a rational number. The fraction is written as p/q, where p represents the numerator and q represents the non-zero denominator. Every integer is regarded as a rational number by this theory. For instance, 5 is both an integer and a rational number since 5/1 = 5. Zero is believed to be a rational number as well and can be represented as 0/2, 0/3, 0/4, etc. A zero, however, cannot be the denominator because it cannot be solved.

What are Rational Number Types?

• Standard form rational numbers and positive and negative rational numbers are the two categories of rational numbers.
• If a number just has the dividend and the divisor as its factors rather than any other common elements, it is said to have a standard form.
• Positive rational numbers are those whose fractions contain both positive and negative digits.
• Rational numbers with a negative value for one of the numbers make up negative numbers.
• When properly comprehended after acquiring all the necessary knowledge, rational numbers can be challenging but also more comfortable and simple.

What are the Rational Number’s Properties?

• Closure Property: When two rational numbers are subjected to an arithmetic operation, the outcome is also a rational number. Under addition, subtraction, and multiplication, rational numbers are closed; however, the division does not.
• Commutative property: Any given arithmetic operator can be used to swap two rational numbers, and the outcome of the expression stays the same. Under addition and multiplication but not division, rational numbers are commutative.
• When we swap the positions of rational numbers between two or more of the same type of arithmetic operators, the outcome remains the same, this is known as the associative property. Under addition and multiplication but not division, rational numbers are associative.
