Work Step by Step
The numbers being added have opposite signs.
The absolute value of the positive number is $\frac{1}{2}$. or $\frac{5}{10}$.
The absolute value of the negative number is $\frac{4}{5}$ 0r $\frac{8}{10}$.
Since the negative number has a higher absolute value than the positive number, then the sum of the two numbers is negative.
