The number of unharmed acres would be $$(\frac{8}{11}+\frac{17}{25}+\frac{17}{25}+\frac{1}{9}+\frac{5}{6}+\frac{6}{7})*27\approx{(0.7+0.7+0.7+0.1+0.8+0.9)*27}\approx{3.9*27}$$ --> 4*27=108, so 3.9*27 is slightly less than that.

P.S. Not a good question.

as mentioned seems poor quality, but as you can see the source , its assumed to be a GMAT type .
It's part of a free Diagnostic test offered by them, so understandably it has got to be Hard so that you prepare well.

It's no problem if you understand that way because they are exactly the same things.
17/25 (A+B) = 17/25A + 17/25B
