Verify that -(-x) = x for
(i) x = 11/15 (ii) x = -13/17
Rational numbers 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)
(ii) x = -13/7
-(-x) = -[-(-13/7)]
Verify that -(-x) = x for. (i) x = 11/15 (ii) x = -13/7
NCERT Solutions Class 8 Maths - Chapter 1 Exercise 1.1 Question 3
By using the additive property of rational numbers, it is verified for parts (i) x = 11/15 (ii) x = -13/7 that -(-x) = x
