Question

нужно решить подробно.

Answer 1

a). (-3,6*0,4 - 2,7)*(-10) = (-1,44 - 2,7)*(-10) = -4,14*(-10) = 41,4
б). -4,04*1,5 - 8,6*(-2,5) = -6,06 + 21,5 = 15,44
в). -5/12 * 2 2/3 - 7 2/3 * (-1/6) = -5/12 * 8/3 + 23/3 * 1/6 =
     = -20/18 + 23/18 = 3/18 = 1/6
г ). (-1 3/7 * 4 2/3 + 1 7/9)*(-3/4) = (-10/7 * 14/3 + 16/9)*(-3/4) =
     = (-60/9 + 16/9)*(-3/4) = 44/9 * 3/4 = 11/3 = 3 2/3
