помогите сделать домашнее задание по математике номер 599

-0.2*(-5)*13 = 1*13 = 13-2.5*(-1.3)*4 = -2.5*4*(-1.3) = -1*(-1.3) = -1.3-0.25*(-0.3)*(-4) = -0.25*(-4)*(-0.3) = 1*(-0.3) = -0.3-4*(-(7/10))*5 = -20*(-(7/10)) = 7*2 = 14-(8/15)*(-(1/2))*(-(3/4)) = -(8/15)*(3/8) = -1/5 = -0.2-(3/4)*(-5)*4 = -3*(-5) = 15
