First write the percent as a fraction. To do this we just write the percent over 100 giving you 38/100 then reduce it to get it in simplest form since the numerator and denominator are both even easiest to do it by 2. First the numerator: 38/2 =19

__19__then the denominator: 100/2=50 Final reduced answer is 50 since 19 is prime your done!!!
