Answers

1. (i) Both expressions simplify toClass 8 Maths - Rational Numbers CBSE Worksheets, which means they are the same. 

(ii) Both expressions are equal, as simplifying both expressions results in the same value, Class 8 Maths - Rational Numbers CBSE Worksheets

2. -125/462

3. 1/2

4. 
(i) -7/19
(ii) 21/112

5. 

We want to verify the equation –(–p) = p, where p = -11/31.

By negating a negative number, we get its positive value, so –(–p) simplifies to p.

Substituting p = -11/31 into the equation, we have:

–(–p) = –(–(-11/31))

Applying the rule of double negation, we get:

–(–p) = –(11/31)

On the right side of the equation, p = -11/31.

Comparing both sides, we see that –(–p) simplifies to -11/31, which matches the value of p.

Therefore, –(–p) = p holds true for p = -11/31.
