5.6×12+7.2×10+1.5×46+4.8×6+18.6×4+12×4.5
=5.6×12+12×6+1.5×46+12×0.4×6+6.2×3×4+12×1.5×3
=12×(5.6+6+2.4+6.2)+1.5×(46+36)
=12×20.2+1.5×2×41
=10×20.2+2×20.2+3×41
=202+40.4+123
=325+40.4
=365.4
=5.6×12+12×6+1.5×46+12×0.4×6+6.2×3×4+12×1.5×3
=12×(5.6+6+2.4+6.2)+1.5×(46+36)
=12×20.2+1.5×2×41
=10×20.2+2×20.2+3×41

答案为365.4,算式可化为5.6*12+2.4*12+6.2*12+4.5*12+7.2*10+1.5*46=(5.6+2.4+6.2+4.5)*12+72+69=18.7*12+141=224.4+141=365.4
