$- 5 \frac{1}{10}$

#### Explanation:

Turn each into an improper fraction.

$2 \frac{2}{5} = \frac{12}{5}$ and $- 2 \frac{1}{8} = - \frac{17}{8}$

$\frac{12}{5} \times - \frac{17}{8}$

Then cross cancel to make it easier.

${\cancel{12}}^{3} / 5 \times - \frac{17}{\cancel{8}} ^ 2$

$12 \mathmr{and} 8 \rightarrow 3 \mathmr{and} 2$.

Then multiply straight across.

$3 \times 17 = 51 , \mathmr{and} 5 \times 2 = 10.$

$\frac{51}{10} = 5 \frac{1}{10}$

but then you have to take the negative sign into account, so the final answer would be $- 5 \frac{1}{10.}$
