Hi there! :)

$\large\boxed{-8.4}$

We can calculate the decimal by converting the fraction to an improper fraction, then dividing.

Derive the inpromper fraction by:

$a\frac{b}{c} = \frac{c * a + b}{c}$

In this instance:

$-8\frac{2}{5} = \frac{-8* 5 -2 }{5} = \frac{-42}{5}$

Divide:

-42 ÷ 5 = -8.4.
