Answer:


a=(6)/(5).

Explanation:

1. Write the expression.


a+(4)/(5) =(1)/((1)/(2) )

2. Convert the right hand side of the equation (check attached image 1).


a+(4)/(5) =1*(2)/(1) \\ \\a+(4)/(5) =2

3. Subtract 4/5 from both sides of the equation.


a+(4)/(5)-(4)/(5) =2-(4)/(5)\\ \\a=(2)/(1)-(4)/(5)\\\\a=(2*5)/(1*5)-(4)/(5)\\ \\a=(10)/(5)-(4)/(5)\\ \\a=(10-4)/(5) \\ \\a=(6)/(5)

4. Verify your answer.


((6)/(5) )+(4)/(5) =(1)/((1)/(2) )\\ \\(10)/(5) =2\\ \\2=2

5. Conclude.


a=(6)/(5).
