Is -2 Rational or Irrational?
Introduction
The concept of rational and irrational numbers has been a topic of discussion for many years. Rational numbers are those that can be expressed in the form of a fraction, whereas irrational numbers cannot be expressed in the form of a fraction. In this article, we will discuss whether -2 is rational or irrational.Rational Numbers
To understand whether -2 is rational or irrational, let us first discuss rational numbers in detail. Rational numbers are those that can be expressed in the form of a fraction where the numerator and denominator are integers. For example, ½, ¾, and 7/8 are all rational numbers.Irrational Numbers
On the other hand, irrational numbers cannot be expressed in the form of a fraction. They are non-repeating and non-terminating decimals. Examples of irrational numbers include pi, e, and the square root of 2.Is -2 Rational or Irrational?
Now that we have discussed rational and irrational numbers, let us answer the question of whether -2 is rational or irrational. -2 can be expressed as -2/1, which is a fraction where the numerator and denominator are integers. Therefore, -2 is a rational number.Properties of Rational Numbers
Rational numbers have various properties. For example, any rational number can be expressed as a decimal, which can either be terminating or repeating. Rational numbers are also closed under addition, subtraction, multiplication, and division.Why is it Important to Understand Rational and Irrational Numbers?
