#31/200#

Explanation:

#15.5%# Express #%# as "part of #100#" (divide by #100#)
#=15.5/100# Multiply the numerator and denominator by 10 to have a whole number on the top and bottom
#=(15.5*10)/(100*10)=155/1000# Since 155 and 1000 both end in 0 or 5, 5 is a factor of both, so divide them both by 5.
#=(155/5)/(1000/5)=31/200#
Since 31 is prime, this must be the simplest form.
