Определите коэфеценты ; 3a×(-8); -5×3/10b;-7c×(-3d); -8c×(-3/4d); 10m×(-0,5n); -9m×(-2/3n)

1) 3 * a * (-8) = -24 * а;

2) -5 * 3/10 * b = -15/10 * b = -1,5 * b;

3) -7 * c * (-3 * d) = 7 * c * 3 * d = 21 * c * d;

4) -8 * c * (-3/4 * d) = 8 * c * 3/4 * d = 6 * c * d;

5) 10 * m * (-0,5 * n) = -5 * m * n;

6) -9 * m * (-2/3 * n) = 9 * m * 2/3 * n = 6 * m * n.
