Question

If $x$ be any rational number then $x+0$ is equal to:

• A. $x$
• B. $0$
• C. $-x$
• D. Not defined

Answer 1

The correct option is A

$x$

Find the value of the given expression

The rational number $0$ is the additive identity for rational numbers, i.e., if $x$ is a rational number.

Then, $x+0=0+x=x$

For example: Consider a number $\frac{1}{3}$. So, when $\frac{1}{3}$ is added to zero, result will be

$\frac{1}{3}+0=\frac{1}{3}$ [By Additive Identity]

Hence, option(A): $x$ is the correct answer.
