Schreibe beide Zahlwörter aus und dividiere die 10 Billionen durch 1 Million.

10 Billionen = $10\cdot {10}^{12}10\backslash cdot10^\{12\}$

1 Million = ${10}^{6}10^6$

$\frac{10\cdot {10}^{12}}{{10}^6}=\frac{{10}^{13}}{{10}^6}={10}^{13-6}={10}^7\backslash frac\{10\backslash cdot10^\{12\}\}\{10^6\}=\backslash ;\backslash frac\{10^\{13\}\}\{10^6\}=10^\{13-6\}\backslash ;=\backslash ;10^7$

$\Rightarrow \backslash ;\backslash ;\backslash ;\backslash ;\backslash Rightarrow\backslash ;\backslash ;$ 10 Millionen mal muss der Koffer gefüllt werden.
