The sum of a rational number and an irrational number is always irrational because it results in a non-terminating decimal.

What are rational and irrational numbers?

  • Rational numbers are numbers that can be represented by fractions, such as terminating decimals.
  • Irrational numbers are numbers that cannot be represented by fractions, such as non-terminating decimals and non-exact roots.

The sum of a terminating decimal with a non-terminating decimal always results in a non terminating decimal, that is, the sum of a rational number with an irrational number is always irrational.

Upon summing the two type of numbers, rational and irrational number, assuming the result upon rearrangement to be a rational number implies a contradiction.

Hence, the basic premise for the conclusion that the sum of a rational and an irrational number yields an irrational number is because, the other way round implies a contradiction.
