x=25/6=4 1/6
Пошаговое объяснение:
-2 11/12=-(2*12+11)/12=-35/12
-1 3/7=-(1*7+3)/7=-10/7
x : (-2 11/12)=(-1 3/7)
x=-10/7*(-35/12)=35/7*10/12=5*5/6=25/6=4 1/6
х = 4 1/6
x : (-2 11/12) = (-1 3/7)
х = (-2 11/12)*(-1 3/7)
х = -35/12 * (-10/7)
х = 25/6
Проверка:
4 1/6 : (-2 11/12) = -1 3/7
25/6 : (-35/12) = -1 3/7
25/6 * (-12/35) = -1 3/7
-10/7 = -1 3/7
-1 3/7 = -1 3/7 - верно
