Question

Answer 1

\(\Rightarrow A=\left(-\dfrac{3}{11}-\dfrac{8}{11}\right)+\dfrac{11}{8}-\dfrac{3}{8}\)

         \(=-\dfrac{11}{11}+\dfrac{11}{8}-\dfrac{3}{8}=-1+\left(\dfrac{11}{8}-\dfrac{3}{8}\right)=-1+1=0\)

Answer 2

\(A=\left[\left(\dfrac{-3}{11}\right)+\left(\dfrac{-8}{11}\right)\right]+\left(\dfrac{11}{8}-\dfrac{3}{8}\right)\\ A=\left(-1\right)+1=0\)

Answer 3

\(\left(-\dfrac{3}{11}\right)+\dfrac{11}{8}-\dfrac{3}{8}+\left(-\dfrac{8}{11}\right)=-\dfrac{11}{11}+\dfrac{8}{8}=-1+1=0\)

Answer 4

\(=\left(\dfrac{-3}{11}-\dfrac{8}{11}\right)+\left(\dfrac{11}{8}-\dfrac{3}{8}\right)\\ =-1+1\\ =0\)

Answer 5

⇒ A = ( − 3/ 11 − 8 /11 ) + 11/ 8 − 3 /8

= − 11/ 11 + 11/ 8 − 3 /8 = − 1 + ( 11/8 − 3 /8 ) = − 1 + 1 = 0
