Statement: The sum of a rational number and an even integer is rational.

Is this always, sometimes, usually, or never true?

Respuesta :

Answer:

Always true.

Step-by-step explanation:

Suppose the rational number was p/q and the even number was 2n where p, q and n are integers.

p/q + 2n

= (p + 2nq) / q  which is rational.
