you have to find a common denomiator first to add the first 2 fractions. This gives you 11/9. Then the 2 negatives make it addition as well so you add that to 11/9 and get 43/18.

2/3 + 5/9 + 7/6 (minus a negative equals positive)
(2/3)(6/6) + (5/9)(2/2) + (7/6)(3/3) (convert to least common denominator, which is 18)
12/18 + 10/18 + 21/18
(12+10+21)/18
43/18

observe: it incredibly isn't probably a riddle. Riddles are somewhat extra imprecise. besides, you have an expression. only use it present day fee = 0.75x - 0.15(0.75x) = 0.75x (one million - 0.15) = x * 0.seventy 5 * 0.80 5 whilst unique fee = $40 8, then present day sale fee = $40 8 * 0.seventy 5 * 0.80 5 = $30.60 ---------------- unique fee = x 1st sale fee = seventy 5% of unique fee = 0.seventy 5 * x 2d sale fee = 15% off of 1st sale fee = 80 5% of 1st sale fee = 0.80 5 * 0.seventy 5 * x
