Concept:

  • Rational numbers are those numbers that show the ratio of numbers or the number which we get after dividing it with any two integers.
  • Irrational numbers are those numbers that we can not represent in the form of simple fractions a/b, and b is not equal to zero.
  • When we add any two rational numbers then their sum will always remain rational.
  • But if we add an irrational number with a rational number then the sum will always be an irrational number.

 

Explanation:

Case:1 Take two irrational numbers π and 1 - π

⇒ Sum =  π +1 - π = 1

Which is a rational number.

Case:2 Take two irrational numbers π and √2 

⇒ Sum =  π + √2

Which is an irrational number.

Hence, a sum of two irrational numbers may be a rational or an irrational number.
