Verify that -(-x) = x for   
(i) x = 11/15    (ii) x = -13/17

Solution:

Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0.

The negative of a negative rational number is the same rational number.

(i) x = 11/15

-(-x) = -(-11/15)

= 11/15

= x

Hence proved

(ii) x = -13/7

-(-x) = -[-(-13/7)]

= -13/7

= x

Hence proved
