not sure how old you are or your level of maths ("math" if you're American), but just put the numbers in the equation, where you see the relevant letter:
% = +%28%28-98.42%29+%2B+%284.15%2Aw%29+-+%280.082%2Ab%29%29%2F%28b%29 gives
% = %28%28-98.42%29+%2B+%284.15%2A32%29+-+%280.082%2A156%29%29%2F156 assuming that the numbers are in the correct units for this equation. Now just work it out...
% = %28-98.42+%2B+132.8+-+12.792%29%2F156
% = 21.588%2F156
% = 0.138
