I just did a very similar problem where you have to find a set of numbers so that when multiplied or added together you get 7. So i just plugged in your 7.11 into my formula and got an answer. Its a bit complicated how I got there. Essentially I used the formula a/b+(a-b)/b+b^2=(whatever number you want). And the formula a/b*(a-b)/b*b^2=(the number you want). Then I plugged in 7.11, combined the two formulas to solve for b. Used my calculator to find the solution (which should be in terms of fourth roots and square roots) and got these numbers. (they are rounded) a=3.121604582 b=.84392981. Notice that each of those equations uses 3 terms (a/b, (a-b)/b, b^2). Those are the three numbers. So finally, the numbers are... 3.698891237, 2.698891237, .7122175253. If you want whole numbers though... I cant help.
