"Fewer" is used when you're talking about an actual number of things and is only used with plural nouns. 

Example: Fewer adults floss daily than they did 20 years ago. (Adults is a plural noun.)

"Less" is used when the amount is undefined and is only used with singular nouns. 

Example: Less than half of adults floss daily. (Half is a singular noun)
