Which of the following is equal to $$\frac{2}{5} \times \left ( \frac{-3}{8} - \frac{4}{5} \right )$$?
$$\frac{2}{5} \times \left ( \frac{3}{8} \right ) - \frac{2}{5} \times \frac{4}{5}$$
$$\frac{2}{5} \times \left ( \frac{-3}{8} \right ) - \frac{2}{5} \times \frac{4}{5}$$
$$\frac{2}{5} \times \left ( \frac{-3}{8} \right ) + \frac{2}{5} \times \frac{4}{5}$$
$$\frac{2}{5} \times \left ( \frac{-3}{8} \right ) - \frac{2}{5} \times \left ( \frac{-4}{5} \right )$$

Click the correct answer.
$$\frac{-7}{11} + \frac{13}{22} + \frac{2}{5} = \frac{13}{22} + \frac{2}{5} +$$
$$\left (\frac{-7}{11} \right )$$
$$\frac{7}{11}$$
$$\left (\frac{-11}{7} \right )$$
$$\frac{16}{31} +$$
$$= 0 + \frac{16}{31} = \frac{16}{31}$$
$$0$$
$$1$$
$$\frac{-16}{31}$$
$$\frac{-3}{4} + \frac{3}{4} =$$
$$0$$
$$\frac{-6}{4}$$
