e)-4/33×27/-8×-11/-9
f) - 3/4×0,2×1/-3×12
g) - 9/11×0,99×50/-3

Answer 1

a) - 1/4×8×-1×6×-1/12=8/4* (-1/2)= -1

b) 7/3×-19/96×-15/14= 7/3*(-19/96)*(-15/14)= ( -133/228)*(-15/14)= 5/8

c) (-2,5)×7,(3)×(-4)=-25/10* 66/9* (-4)= 220/3

d) - 2intr. 1/4×- 3intr. 1/5×10= -9/4*(-16/5) *10=36/5*10= 72

e)-4/33×27/-8×-11/-9=(-4/33)×(-27/8)*8×11/9=9/22*88/9= 4

f) - 3/4×0,2×1/-3×12= -3/4 * 1/5*(-1/3)*12= 3/5

g) - 9/11×0,99×50/-3 = (-9/11)* 99/100* (-50/3)= 27/2
