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?

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.
