To solve the equation $m - \frac{2}{5} = \frac{1}{2}$ using the addition principle, add $\frac{2}{5}$ to both sides to isolate $m$. This gives $m = \frac{1}{2} + \frac{2}{5}$. To add these fractions, find a common denominator, which is 10. This results in $m = \frac{5}{10} + \frac{4}{10} = \frac{9}{10}$.
