#3/1000#

Explanation:

A percentage is actually just a part out of 100. So for example, 10% is the same as 10 out of a 100 or #10/100# which simplifies to #1/10#.

In this case we see #0.3%# which is like saying #0.3/100#. Of course we do not want decimals in the numerator (the same way we wouldn't want a fraction in the numerator of a fraction). So to fix this we could multiply by #10/10# (which is to say #1#) to make #0.3# into a whole number.

#0.3/100 * 10/10 = 3/1000# and cannot be simplified.
