A. is the one which can be represented in the form of P/Q where P and Q are integers and Q ≠ 0. #Rule 4: The product of two irrational numbers is not always irrational. But an irrational number cannot be written in the form of simple fractions. 0.5 can be written as ½, 5/10 or 10/20 and in the form of all termination decimals. Now, let us elaborate, irrational numbers could be written in decimals but not in the form of fractions which means it cannot be written as the ratio of two integers. And so on. As you can see, #-12# is an integer, but it is also a rational number because it can be made into a fraction: #-12/1# and it is real because it can be found on the number line. Wolfram alpha paved a completely new way to get knowledge and information. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. Pi (π) is an irrational number and hence it is a real number. log 2 is irrational , however it is approximately in the common logarithmic tables for practical purposes. Rational and Irrational numbers both are real numbers but different with respect to their properties. #Rule 2: The product of two rational number is rational. 0.7777777 is recurring decimals and is a rational number. Which natural numbers have rational square roots? Rational numbers are finite and repeating decimals whereas irrational numbers are infinite and non-repeating. Therefore, any number added to an irrational number will result in an irrational number only. It can be written as p/q, where q is not equal to zero. Rational number. Rational word is derived from the word ‘ratio’, which actually means a comparison of two or more values or integer numbers and is known as a fraction. Examples of rational numbers are ½, ¾, 7/4, 1/100, etc. The square roots of the square numbers are the only square roots that we can name.
