简便运算,(-5/12+2/3-5/6+3/8)*(24*5/9-24*2/9+24*2/3)
简便运算,
(-5/12+2/3-5/6+3/8)*(24*5/9-24*2/9+24*2/3)

简便运算,(-5/12+2/3-5/6+3/8)*(24*5/9-24*2/9+24*2/3)
(-5/12+2/3-5/6+3/8)*(24*5/9-24*2/9+24*2/3)
=(-10+16-20+9)/24*(24*5/9-24*2/9+24*6/9)
=(-5/24)*24*5/9-(-5/24)*24*2/9+(-5/24)*24*6/9
=-25/9+10/9-20/9
=(-25+10-30)/9
=-45/9
=-5

(-10/24+16/24-20/24+9/24)*(24*5/9-24*2/9+24*2*3/9)=(-5/24)*(216/9)=-5
