1.	Verify associativity of addition of rational numbers i.e., (x+y)+z=x+(y+z) when: (i) x=12,y=23,z=−15 (ii) x=−25,y=43,z=−710 (iii) x=−711,y=2−5,z=−322 (iv) x=−2,y=35,z=−43
Answer» Verify associativity of addition of rational numbers i.e., $(x + y) + z = x + (y + z)$ when: (i) $x = \frac{1}{2}, y = \frac{2}{3}, z = - \frac{1}{5}$ (ii) $x = \frac{- 2}{5}, y = \frac{4}{3}, z = \frac{- 7}{10}$ (iii) $x = \frac{- 7}{11}, y = \frac{2}{- 5}, z = \frac{- 3}{22}$ (iv) $x = - 2, y = \frac{3}{5}, z = \frac{- 4}{3}$

Verify associativity of addition of rational numbers i.e., $(x + y) + z = x + (y + z)$

when:

(i) $x = \frac{1}{2}, y = \frac{2}{3}, z = - \frac{1}{5}$

(ii) $x = \frac{- 2}{5}, y = \frac{4}{3}, z = \frac{- 7}{10}$

(iii) $x = \frac{- 7}{11}, y = \frac{2}{- 5}, z = \frac{- 3}{22}$

(iv) $x = - 2, y = \frac{3}{5}, z = \frac{- 4}{3}$
