Not even one unit > fraction cann be smaller than all positive x. Huh? Say x = 1/2, there are infinite smaller unit fractions, say, 1/4, 1/5, 1/6, ect... However there is only one larger one, 1/1. See? No smallest one for 1/0 is not a unit fraction! There is a largest one, 1/1... They tend to zero, but there is no smallest one... See?
