Пошаговое объяснение:
[(5/2 + 10/3) : (5/2 - 4/3)]:[(23/5 + 7/3) : (23/5 - 7/3)] = [(15/6 + 20/6) : (15/6 - 8/6)] : [(69/15 + 35/15) : (69/15 - 35/15)] = (35/6 : 7/6) : ( 104/15 : 34/15) = [(35*6)/6*7]:[(104*15/34*15)] = (35/7) : (104/34) = 5 : 104/34 = (5 * 34) / 104 = 170 / 104 = 1 целая и 70/104
