Answer
$2\times10^{-8}$
Work Step by Step
$$\frac{4.8\times10^{-2}}{2.4\times10^{6}}$$
Regroup like terms then simplify
$$=(\frac{4.8}{2.4})(\frac{10^{-2}}{10^{6}})$$
When dividing exponential expressions with the same non-zero base, subtract the exponent of the denominator from the exponent of the numerator.
$$=2\times10^{(-2-6)}$$
$$=2\times10^{-8}$$
