Question

0,125а×(-4b)×(-2c)
2)-3/4x×(-2/3y)×(1/2z)
3)-0,15R×(-4m)×(-5n)
4)-6/7a×(5/6b)×(-4/5c)×(-3/4b)

Answer 1

1) 0,125а*(-4b)*(-2c)=abc
2) $- frac{3}{4} x*(- frac{2}{3} y)* frac{1}{2} z= frac{3*2}{4*3*2} xyz= frac{1}{4} xyz=0,25xyz$
3) -0,15R*(-4m)*(-5n)=-3Rmn
4) $- frac{6}{7} a* frac{5}{6} b*(- frac{4}{5} c)*(- frac{3}{4} b)=- frac{6*5*4*3}{7*6*5*4} ab ^{2} c=- frac{3}{7} ab ^{2} c$
