Nov 14, 2016

$\left(\frac{8.8}{4}\right) \times \left({10}^{-} \frac{8}{10} ^ - 7\right)$ or $2.2 \times {10}^{-} 1$ or $0.22$

#### Explanation:

$\frac{8.8 \times {10}^{-} 8}{4 \times {10}^{-} 7} \implies$

$\left(\frac{8.8}{4}\right) \times \left({10}^{-} \frac{8}{10} ^ - 7\right)$

$2.2 \times {10}^{- 8 - \left(- 7\right)}$

$2.2 \times {10}^{- 8 + 7}$

$2.2 \times {10}^{-} 1$

$2.2 \times \frac{1}{10} ^ 1$

$2.2 \times \frac{1}{10}$

$\frac{2.2}{10}$

$0.22$
