1)1 1/3=1,3333~~1,333
1,333-1,333(3)=0,000(6)
2)3/7=0,428571~~0,429
0,429-0,428571=0,0004 2 9
3)2 4/11=2,3636 ~~2,364
2,364-2,3636(36)=0,000364
4)5 7/12=5,6916666~~5,692
5,692-5,691666=0,000334
-3x³y⁴x⁵*4y³ = -12x⁸y⁷
(-4a⁶b)³ = -64a¹⁸b³
Вроде так.................
12*(-3/4)=-9
3*(5/6)=2,5
-9-2,5=-11,5
