let's say they have "x" employees in total, so, that's the 100% of their workforce.
now, if we take "x" to be the 100%, and we know 26900 is 16.9%, what the dickens is "x" anyway?
[tex]\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
x&100\\
26900&16.9
\end{array}\implies \cfrac{x}{26900}=\cfrac{100}{16.9}\implies x=\cfrac{26900\cdot 100}{16.9}[/tex]
now, you get a decimal figure, I take you need to round it up to a whole number.
the decimal result is likely due to any rounding up done to the 16.9.
