Answer 2

Given: $-5+(\frac{-5}{9} )$

We have to solve the above expression.

We are solving in the following way:

We have,

$-5+(\frac{-5}{9} )$

$=>-5-(\frac{5}{9} )$

First, we will multiply $-5\ by\ 9$then we will subtract the number by$5$.

Now,

$=>\frac{(-5\times9)-5}{9} \\\\=>\frac{(-45)-5}{9} \\\\=>\frac{-50}{9}$

Solving the above equation further we get,

$-5.55$

Hence, the solution of the above expression is$\frac{-50}{9}$ or$-5.55$
