I played around with his post and I got a numerical result. May I post it?

givens:
(a/x) = (b/k)
(a/2b) = d(3x/k)

problem;
Find the vaule of "d"

From (a/x) = (b/k),
cross multiply,
bx = ak

From the (a /2b) = d(3x /k),
a/ 2b = 3dx /k
Cross multiply,
2b(3dx) = ak
6bdx = ak

ak = ak,
bx = 6bdx
1 = 6d
