Пошаговое объяснение:
-3(1,2*15/22-2)-(4-4,6*15/22)+6(0,2*15/22-1)= - 2,5
1) -3(1,2*15/22-2)=-3(12/10*15/22-2)=-3(18/22-44/22)= - 3*(-26/22)=39/11=78/22
2) 4-4,6*15/22=4-23/5*15/22=4-69/22=88/22-69/22=19/22
3) 6(0,2*15/22-1)=6(1/5*15/22-1)=6(3/22-1)=6*(-19/22)= - 114/22
4) 78/22-19/22-114/22= - 55/22= - 2,5
