$100{\displaystyle \frac{\text{km}}{\text{h}}}=(100:\mathrm{3,6}){\displaystyle \frac{\text{m}}{\text{s}}}=27,\bar{7}{\displaystyle \frac{\text{m}}{\text{s}}}\approx \mathrm{27,8}{\displaystyle \frac{\text{m}}{\text{s}}}100\backslash dfrac\{\backslash text\{km\}\}\{\backslash text\{h\}\}=(100:3\{,\}6)\backslash dfrac\{\backslash text\{m\}\}\{\backslash text\{s\}\}=27,\backslash overline\{7\}\backslash dfrac\{\backslash text\{m\}\}\{\backslash text\{s\}\}\backslash approx\; 27\{,\}8\backslash dfrac\{\backslash text\{m\}\}\{\backslash text\{s\}\}$

Zur Umrechnung in $\frac{\text{m}}{\text{s}}\backslash frac\{\backslash text\{m\}\}\{\backslash text\{s\}\}$ teilst du $100100$ durch $\mathrm{3,6}3\{,\}6$.
