Given data:

The given expression is 1 4/5 + (2 3/20 + 3/5).

The given expression can be written as,


\begin{gathered} 1(4)/(5)+(2(3)/(20)+(3)/(5)_{})=(9)/(5)+((43)/(20)+(3)/(5)) \\ =(9)/(5)+(43+12)/(20) \\ =(9)/(5)+(55)/(20) \\ =(36+55)/(20) \\ =(91)/(20) \end{gathered}

Thus, the value of the given expression is 91/20.
