Given the expression:


-1(4)/(5)+(-(1)/(4))+(-(1)/(5))

Let's simplify the expression.

Remove the parentheses:


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

COnvert the first fraction from mixed fraction to improper fraction:


-(9)/(5)-(1)/(4)-(1)/(5)

Now, let's find a common denominator using the Lowest Common Multiple(LCM) of the denominators and evaluate.

LCM of 5, 4, and 5 = 20

Divide the LCM by each denominator and multily by the corresonding numerator.


\begin{gathered} (-36-5-4)/(20) \\ \\ =(-45)/(20) \\ \\ =-(9)/(4) \\ \\ =-2(1)/(4) \end{gathered}

ANSWER:


-2(1)/(4)
