44.4x1.2+1.11x52简便计算44.4x1.2+1.11x52简便计算44.4x1.2+1.11x52简便计算44.4x1.2+1.11x52=1.11x40x1.2+1.11x52=1.1

44.4x1.2+1.11x52简便计算
44.4x1.2+1.11x52简便计算

44.4x1.2+1.11x52简便计算
44.4x1.2+1.11x52
=1.11x40x1.2+1.11x52
=1.11x(48+52)
=1.11x100
=111

44.4x1.2=4*11.1*1.2=11.1*4.8=1.11*48
44.4x1.2+1.11x52=1.11*(48+52)=111
