Multiply the probabilites.
You know that 1/5 of workers drive, so you know that 4/5 of them don't.
Of the 4/5 that don't drive, 3/16 ride bicycles. So 4/5 x 3/16 of everybody going to work rides a bike.
4/5 x 3/16 = 12/80 = 3/20

I agree with Psycho
5/5 = the total downtown workers
4/5 = the workers that do not drive
1/5 = the workers that drive
3/16 = the workers that ride bicycles
- - - - - - - - - - - - -
4/5 x 3/16 = 12/80 0r 3/20
The fraction of workers that ride bicycles to work is 3/20
The answer is 3/20

5/5 - 1/5 = 4/5
3/16 x 4/5 = 12/80
Simplify and get 3/20
