If x be any rational number then x + 0 is equal to
(a) x
(b) 0
(c) - x
(d) Not defined

Solution:

Given x + 0

We know that adding 0 to any number gives the same result.

Here, 0 is added to x, which makes no difference in the result

Hence, x + 0 = x

✦ Try This: If 2/3 be any rational number then 2/3 + 0 is equal to (a) 2/3, (b) 0, (c) - 2/3, (d) Not defined

Given 2/3 + 0

We know that adding 0 to any number gives the same result.

Here, 0 is added to 2/3, which makes no different in the result

Hence, 2/3 + 0 = 2/3
