Answer 1

  

Answer 2

\(2+\dfrac{1}{1+\dfrac{1}{2}}\) 

\(=2+\dfrac{1}{\dfrac{3}{2}}=\dfrac{8}{3}\)

Answer 3

\(2+\dfrac{1}{1+\dfrac{1}{2}}\\ =2+\dfrac{1}{\dfrac{2}{2}+\dfrac{1}{2}}\\ =2+\dfrac{1}{\dfrac{3}{2}}\\ =2+1\times\dfrac{2}{3}\\ =2+\dfrac{2}{3}\\ =\dfrac{6}{3}+\dfrac{2}{3}\\ =\dfrac{8}{3}\)
