Given;

[tex]-\frac{7}{10}-(-\frac{5}{10})[/tex]

First, we take out the bracket by multiplying the signs, we have;

[tex]-\frac{7}{10}+\frac{5}{10}[/tex]

Then, since the denominators are equal, we add the numerators, we have;

[tex]\begin{gathered} =\frac{-7+5}{10} \\ =-\frac{2}{10} \end{gathered}[/tex]

Also, the fraction can be simplified or reduced to;

[tex]-\frac{2}{10}=-\frac{1}{5}[/tex]
