Let's break down the expression $-0.5 \times \left(\frac{-2}{5}\right)$ step by step:

1. First, handle the signs. Multiplying two negative numbers results in a positive number: $-0.5 \times \left(\frac{-2}{5}\right) = 0.5 \times \left(\frac{2}{5}\right)$

2. Now, multiply $0.5$ by $\frac{2}{5}$. Recall that $0.5 = \frac{1}{2}$, so the expression becomes: $\frac{1}{2} \times \frac{2}{5} = \frac{1 \times 2}{2 \times 5} = \frac{2}{10}$

3. Simplify $\frac{2}{10}$: $\frac{2}{10} = \frac{1}{5}$

Thus, the simplified result of $-0.5 \times \left(\frac{-2}{5}\right)$ is $\frac{1}{5}$.
