With a bit of imagination, anything is possible. I tried it myself for two seconds before looking it up.
I found the answer on page 192 in The Canterbury Puzzles and Other Curious Problems.
You not only arrange three nines, but you also introduce a bit of mathematical notation (a plus sign, a ratio, and a decimal point).
The answer is (9+9)/.9
In adding 9 and 9 you get 18. You then divide it by .9 (or 9/10).
18/(9/10) = (18*10)/9 = 180/9 or 2*10 = 20
Or you could just pop it into a calculator and get 20 that way.
When I first saw the question, I thought you wanted the numbers to look like '20'.
With a bit of imagination, anything is possible. After all, 9+9=21.

Well, honey, there are nine nines in a billion. Simple as that. Just count those zeros and you'll see it for yourself. Don't make it harder than it needs to be, darling.
