(a) False

(b) True

The question was posed to me in exam.

My query is from Irrational and Rational Numbers in portion Real Numbers of Mathematics – Class 10

Answer 1

The correct answer is (b) True

Easiest explanation: Consider two rational numbers, say \(\frac {8}{9}, \frac {3}{5}\)

Sum of these number = \(\frac {8}{9} + \frac {3}{5} = \frac {67}{45}\), which is rational number.

Hence, the sum of two rational numbers is a rational number.
