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.
