Question

8. For any rational number a and b, a – b = b - a. true or false​

Answer 1

Answer:

have a nice ☺️☺️day

Step-by-step explanation:

true (TRUE)

Answer 2

It is false.

For example taking,

$a = \frac{2}{3} \: and \: b = \frac{1}{3} \\ a - b = \frac{2}{3} - \frac{1}{3} = \frac{1}{3} \\ b - a = \frac{1}{3} - \frac{2}{3} = \frac{ - 1}{3}$

From the above we conclude that for any rational number,a - b is not equal to b - a.
