Answer 1

Пошаговое объяснение:

а) (-2)1/6 - (3)1/4 = - ((2*6+1)/6 - (3*4+1)/4) = - (13/6) - 13/4 = - ((2*13)/(2*6)) - (3*13)/(3*4) = -(26/12) - (39/12)= (-26-39)/12 = -(65/12) = - (5(5/12));

-(5(5/12)) : 2(3/5) = - ((5*13+5)/13) : (2*5+3)/5 = -(70/13) : 13/5 = -(70/13)*(5/13) = -((70*5)/(13*13)) = -(350/169) = -2(12/169);

-2(12/169) + 2/3 = - (2*169+12/169) + 2/3 = -(350/169) + 2/3 = -((3*350)/(3*169)) + (169*2)/(169*3) = -(1050/507) + (338/507) = (-1050+338)/507=-(712/507)= -1(205/507);

-1(205/507) - 2(1/4) = -((1*705+205)/507)-(2*4+1)/4 = -(712/507)-9/4 = -((4*712)/(4*507)) - (507*9)/(507*4) = -((2848/2028)-(4563/2028)) = (-2848-4563)/2028 = -(7412/2028) = -3(1327/2028);

-3(1327/2028) - 5(1/6) = -((3*2028+1327)/2028) - (5*6+1)/6 = -(7411/2028)-(10478/2028) = (-7411-10478)/2028 = -(17889/2028) = -((5963*3)/(676*3)) = -(5963/676)=-8(555/676)

сейчас буду третий решать)
