Difference between rational and irrational numbers class 9

Rational and Irrational numbers both are real numbers but different with respect to their properties.

Learn the definitions, more differences and examples based on them. Irrational Numbers: The real numbers which cannot be expressed in the form of the ratio of two integers are called irrational numbers. We can represent rational numbers in the form of the ratio of two integers positive or negative , where the denominator is not equal to 0. But we cannot express irrational numbers in the same form. Q2 Give examples of rational and irrational numbers. Q3 How can we identify if a number is rational or irrational? If a number has a non-terminating and non-repeating decimal, it is irrational, for example, o.

Rational and irrational numbers comprise the real number system. This Venn diagram shows a visual representation of how real numbers are classified. These are all positive, non-decimal values starting at one. Whole numbers are the natural numbers plus the value of zero. The integer set of numbers includes whole numbers and all negative, non-decimal values. Rational numbers include the sets seen here in addition to the fractional values in between. An easy way to remember this is that the word ratio is in the name of this classification. All numbers included in the rational number set can be written as a ratio of integers:. Clearly, the set of integers can be written as ratios because any integer divided by 1 results in the original integer. As illustrated here, integers can be expressed as fractions in infinite numbers of ways. Fractions can also be written as decimals. For example:. These decimals can be written as fractions, so they are considered rational. Other decimals have repeating patterns. These are also considered rational because they can be expressed as a fraction based on the following proof:.

Real numbers are further categorized into rational and irrational numbers. In this article, we will discuss rational numbers, irrational numbers, Rational and irrational numbers examples, the difference between irrational and rational numbers etc. Rational Numbers.

Irrational numbers are those real numbers that cannot be represented in the form of a ratio. In other words, those real numbers that are not rational numbers are known as irrational numbers. Hippasus, a Pythagorean philosopher, discovered irrational numbers in the 5th century BC. Unfortunately, his theory was ridiculed and he was thrown into the sea. But irrational numbers exist, let's have a look at this page to get a better understanding of the concept, and trust us, you won't be thrown into the sea. Rather, by knowing the concept, you will also know the irrational number list, the difference between irrational and rational numbers, and whether or not irrational numbers are real numbers. Also, the decimal expansion of an irrational number is neither terminating nor repeating. Irrational numbers are real numbers that cannot be represented as a simple fraction. It is a contradiction of rational numbers.
