exactly the reverse
period = time/rev = 68/16
always watch the units
16/68 is how much of a revolution it makes in 1 second.
If it takes an object 68 seconds to make 16 rotations, what would be the period of rotation?
T=16/68
Is this right?

Not to mention you rarely use rev/sec in a Physics class. Rad/sec is more correct:
16(2pi)/68
16(2pi)/68
so rad/sec is better than time/rev?
generally, yes, though in this problem, all you wanted was the time period, in seconds.
