1) -3м×(-2,1)= 6,3м.

2)3,6×(-5х)=-18х.

3)10м×(-1,7)×n= -17мn.

4)-7×3b×(-6с)=126abc.

5)

$16x \times ( \frac{ - 8}{15}b) \times \frac{45}{64}k = 16x( \frac{ - 8}{15}b) \times \frac{45}{64}k = - x \times 8b \times \frac{3}{4}k = - x \times 2b \times 3k = 6bkx$

6)-0,2×(-5a)×(-6)=-0,2t×5a×(-6)=-0,2t-5ab.

1)=-(1,25)×3,47×8=-(10×3,47)=-34,7.

2)=-(0,001×54,8×50×2)=-(0,001×2740×2)=-(0,001×5480)=-5,48.

3)=9×11×2×2=396.

4)=24/5×(-13/6)×(-5/24)×(-6/13)=-1.
