Significant Figures: 1, 2, 3, 4 or 5?

[Victor Frankenstein]

How many significant figures should be retained in the result of the following calculation.

(11.13 - 2.6) * 10^4
-----------------------
(103.05 + 16.9) * 10^-6

is it 1 , 2 , 3 , 4 or 5 ?

I just read the posting guidelines more closely, so instead i will give u a hint :-)
You should look at the entire "formula" (I lack a better word), and find the number with least significant digits, that's the amount of significant digits in your final result.
