-2 5/12+11/18-1/6=-- приведем все к одному знаменателю-- это 36.
-29/12+11/18-1/6= -29*3+11*2-1*6 = -87+22-6 = -71/36 =- 1 35/36

-2 5/12*(-2 1/12)+11/18-1/6 = 667/144+11/18-1/6 = 755/144-1/6 = 5 11/144
1) -2 5/12*(-2 1/12) = -29/12*(-23/12) = 667/144
2) 667/144+11/18 = 667/144+88/144 = 755/144
3) 755/144-1/6 = 755/144-24/144 = 731/144 = 5 11/144
