Oct 5, 2016

0.002 or $2 \times {10}^{-} 3$

#### Explanation:

Note that ${10}^{- 3}$ is another way of writing $\frac{1}{{10}^{3}}$

0.008 can be written as $8 \times {10}^{-} 3$

The problem can be written as $\left(\frac{8}{4}\right) \times {10}^{-} 3$

$\frac{8}{4}$ = 2 Which gives

$2 \times {10}^{-} 3$ or 0.002
