## 10. How are rational and irrational numbers related? - Socratic

Apr 9, 2016 · Rational and irrational numbers are mutually exclusive but jointly or collectively exhaustive set of real numbers. Explanation:.

Rational and irrational numbers are mutually exclusive but jointly or collectively exhaustive set of real numbers. The set of rational numbers and irrational numbers are unique The two most important features are: (1) They are mutually exclusive i.e. a number from one set say Rational numbers QQ cannot be a member of another set that is irrational numbers ZZ and vice-versa. In set theory, we say that the intersection of QQ and ZZ is phi, the null set or QQnnZZ=phi. This is because while rational numbers can be written as a ratio of two integers say p/q, where p and q are integers and q!=0, irrational numbers cannot be written as such. In decimal notation, while rational numbers are terminating after decimal sign or have non-terminating but repeating (or recurring decimals), irrational numbers have non-terminating non-repeating (or non-recurring decimals). (2) However, together they form the set of Real numbers RR and both rational and irrational numbers can be represented on real number line and in set theory we say that QQuuZZ=RR and there are no real numbers, which do not fall in one or he other category. In short, we can say that rational and irrational numbers are mutually exclusive but jointly or collectively exhaustive set of real numbers.

## FAQs

### Can A Number Be Both Rational And Irrational? ›

e) A number that belongs to the set of rational numbers cannot belong to the set of irrational numbers. Any number that cannot be written as a rational number is an irrational number. Therefore **it is never true that a number can be both rational and irrational**.

**Can something be rational and irrational at the same time? ›**

**The answer is no**. However, just because we cannot answer a question by way of rationality, doesn't automatically mean that the response will be irrational. Generally, when people think about rationality, they assume that it works as a binary. Things are either rational or irrational.

**What numbers include both rational and irrational numbers? ›**

All natural numbers are integers but not all the integers are natural numbers. These are the set of all counting numbers such as 1, 2, 3, 4, 5, 6, 7, 8, 9, …….∞. **Real numbers** are numbers that include both rational and irrational numbers.

**Can a number be both an irrational number and a rational number True or false? ›**

Rational numbers can never be irrational. Numbers are either rational or not. **They cannot be both rational and irrational**.

**Can rationality be irrational? ›**

Rational irrationality describes a situation in which it is instrumentally rational for an actor to be epistemically irrational. Caplan argues that rational irrationality is more likely in situations in which: people have preferences over beliefs, i.e., some kinds of beliefs are more appealing than others and.

**Is the number 65.4349224 rational or irrational? ›**

because it has terminating digits after decimal. Hence, 65.4349224 is a **rational number**.

**What is a number that is both real and irrational? ›**

Any one number cannot possibly be both since that would make it both writeable as a fraction and impossible to write as a fraction. **The entire set of Real Numbers does contain both rational and irrational numbers**, if that was supposed to be the question, but no single number can be both.

**Is 8.141141114 rational or irrational? ›**

Answer: 8.141141114 is **not a rational number** as it has non-terminating decimal representation.

**Is 7 rational or irrational? ›**

7 is a **rational number** because it can be written in the form of a ratio such as 7/1.

**Can real numbers either be rational or irrational? ›**

Thus, we can say that numbers which are not rational numbers are called irrational numbers. If we combine the rational numbers and the irrational numbers, we get real numbers. Hence, **all real numbers are not rational numbers** because real numbers also contain irrational numbers.

### Can a number be both negative and irrational? ›

Irrational numbers are not rational—they are real numbers that we cannot write as a ratio pq (where p and q are integers, with q≠0). The reason we don't allow q=0 is because we cannot divide by zero. Also, **irrational numbers can be positive or negative**.

**How do you combine rational and irrational numbers? ›**

**The sum of any rational number and any irrational number will always be an irrational number**. This allows us to quickly conclude that ½+√2 is irrational.

**Can both rational and irrational numbers be negative? ›**

Explanation: **Yes, rational and irrational numbers can be negative**. Te only thing that is desired is that they could be mapped to a place on a real number line. Negative numbers are to the left of 0 on number line.

**What is a rational being and an irrational being? ›**

Rational behavior is a trait of an individual whose decisions are based on sensible reasoning. Irrational behavior is the behavior of an individual who favors emotion and disregards logic and reasoning.

**What is an example of a rational and irrational number? ›**

**Rational numbers include perfect squares such as 4, 9, 16, 25, and so on.** **Irrational numbers include surds such as √2, √3, √5, √7 and so on**. Both the numerator and denominator are integers, in which the denominator is not equal to zero. Irrational numbers cannot be written in fractional form.
