...assuming a doesn't equal 0 (since that would mean it isn't truly a three digit number) I'd be curious to see a smaller value of M / (a + b + c)

I'm going to stick by 199/19 = 10.473684210...

you are right in that a does not equal to zero but there is still a smaller answer

I get

a = -9

b = 1

c = 9

100*a + 10*b +1*c = M = -881

M/(a+b+c) = -881

a b and c are digits not integers, good idea though. If they were integers there would still be smaller answer then what you have found here. can you find that answer too?

a=-9 b=0 c=9 d= -infinity and any similar variation.

I also get a=1 b=9 c=9 d=10.47368.....

I disagree with your first solution (well) since it is undefined, we don't know if the value is defined to mean min or max as it is undefined
