$\frac{(4\times10^7)(6\times10^5)}{8\times10^4}$

✓

Answer

$\frac{(4\times10^7)(6\times10^{-4})}{8\times10^4}$

$\frac{(4\times10^7)(6\times10^5)}{8\times10^4}$

$\frac{(24\times10^7\times10^{-5})}{8\times10^4}$

$=\frac{24\times10^{7-5}}{8\times10^4}$

$=\frac{24\times10^{2}}{8\times10^4}$

$=\frac{(3\times10^2)}{10^4}$

$=\frac{3}{100}$
