"Percent" or "%" means "out of 100" or "per 100", Therefore 0.4% can be written as:

#0.4/100#

Or, if we multiply by the numerator and denominator by #10/10# which is the same as multiplying by #1# we obtain:

#0.4/100 xx 10/10 = 4/1000#

Or, we can factor to get:

#4/1000 = (2 xx 2)/(2 xx 2 xx 250) = cancel(2 xx 2)/(cancel(2 xx 2) xx 250) = 1/250#

The solution is: #0.4/100# or #4/1000# or #1/250#
