1. а) 6*(-12у) = -72у (коэф. = -72)
б) -0,7а*(-1 3/7b) = 7/10 * 10/7 * ab = ab (коэф. = 1)
в) х*(-3у)*(-z)*(-t) = -3xyzt (коэф. = -3)
г) -х*(-5 1/4у)*5 1/3 = 21/4 * 16/3*ху = 7*4*ху = 28ху (коэф. = 28)
д) -pqt * (-17 2/41) = 17 2/41 pqt (коэф. = 17 2/41)

2. а) (21 47/99 - 28 6/35) - (21 47/99 - 3 9/28) = 21 47/99 - 28 6/35 - 21 47/99 +
+ 3 9/28 = -28 6/35 + 3 9/28 = -28 24/140 + 3 45/140 = -27 164/140 + 3 45/140 =
= - 24 119/140 = - 24,85
б) 7 3/19 * (-5 4/5) - 7 3/19 * 5 3/5 = 7 3/19(-5 4/5 - 5 3/5) = 7 3/19 * (-10 7/5) =
= 136/19 * (-57/5) = -408/5 = -81,6
