Question

If both a and b are rational numbers , find value of a and b of expression
= a+b​

Answer 1

❥ a + b = a rational number ( let c)

If a and b are rational numbers, then their sum will also be a rational number as rational numbers are closed under addition.

you can check it by practical approach :

• 2 (rational) + 6.5 (rational) = 8.5(Rational)
• 3/2(Rational) + 1/2 (Rational) = 4/2 = 2(rational).....

i think the question is incomplete ☺️
