The given expression is :


3(4)/(5)-1(3)/(5)

Express the mixed fraction in the fraction form :


\begin{gathered} 3(4)/(5)=(3*5+4)/(5) \\ 3(4)/(5)=(19)/(5) \\ \\ 1(3)/(5)=(1*5+3)/(5) \\ 1(3)/(5)=(8)/(5) \end{gathered}

Substitute the value :


3(4)/(5)-1(3)/(5)=(19)/(5)-(8)/(5)

Simplify: Since the denominator are same so equate the numertor value together :


\begin{gathered} 3(4)/(5)-1(3)/(5)=(19)/(5)-(8)/(5) \\ 3(4)/(5)-1(3)/(5)=(19-8)/(5) \\ 3(4)/(5)-1(3)/(5)=(11)/(5) \end{gathered}

Express 11/5 in terms of mixed fraction :


\text{ If }(a)/(b)\text{ then the mixed fraction has Quotient}\frac{\operatorname{Re}maider}{Divisor}

So, divide 11/5 :

So :


(11)/(5)=2(1)/(5)


3(4)/(5)-1(3)/(5)=2(1)/(5)

Now express in the deimal form :

So, 11/5 = 2.2


3(4)/(5)-1(3)/(5)\text{ = 2.2}

Answer : 3 4/5 -1 3/5​ = 2 1/5, 3 4/5 -1 3/5​ = 11/5 or 3 4/5 -1 3/5​ = 2.2
