A certain set of positive integers (a,b,c) causes the sum of their reversals (i.e. S=1/a+1/b+1/c) to be the closest to 1/2 without equaling or exceeding it.

Find S.
Explain your method.

(In reply to Possible solution by broll)

Is that the solution to a different problem? S must be close to but under 1/2.
