In order to calculate the total number of employees, we can use the following rule of three:
[tex]\begin{gathered} employees\rightarrow percentage \\ 21300\rightarrow32.4\% \\ x\rightarrow100\% \end{gathered}[/tex]Now, from this rule of three, we can write the following proportion and solve it for x:
[tex]\begin{gathered} \frac{21300}{x}=\frac{32.4}{100}\\ \\ x\cdot32.4=21300\cdot100\\ \\ x=\frac{21300\cdot100}{32.4}\\ \\ x=65740.74 \end{gathered}[/tex]Rounding to the nearest whole number, the total number of employees is 65741.
