You do realise that by putting limits on the denominator, you guarantee
that the sum of the fractions also has a limit on the denominator? In
other words, your "test" is useless.
With denominators limited to 1 through 9 inclusive, the sum will have a
denominator of 2*3*5*7 = 210. But that limit is a product (literally and
figuratively) of your artificial limit on the denominator. Add a fraction
with denominator 11, and the sum now has a denominator of 2310; add
another fraction n/13 and the sum goes to m/30030; and so on.
