np 1/7 to jakby jedna siodma (3,75+3,75) x (9 1/7) = (4/5) x (15) - 1 1/3 x (1,2) = (3 3/5) : (3/5) x 5 = (3 3/5 : [(3/5) x 5] = 1,8 : [(0,2) x 0,3] = 1,8 : (0,2) x 0,3 = (2,4) x 3/7 - 4,6 x 3/7 = (5,6) x 0,75 - 2 2/5 x 0,75 = 9:1,5 - [(2,7) x (2/18) - 3/20 x 2] = (1 1/3) x 0,75 - (1,25) x (0,8) = Prosze o obliczenia Daje naj :D Po tym = prosze o odp .. A po = jest nastepny przyklad :D
