7.7乘5分之1加0.43乘22=7.7×0.2+0.43×22=1.1×7×0.2+0.43×22=22×(0.7+0.43)=22×0.5=11
=3.78×47.2＋3.78×10×5.28=3.78×4.72＋3.78×52.8＝3.78×（47.2＋52.8）＝3.78×100＝378

您好：72乘15加24乘29加24乘26=72x15+24x(29+26)=72x15+24x54=72x15+24x3x18=72x(15+18)=72x33=72x30+72x3=2160+216
设那数为X0.27*5.6+5.6X+5.6*0.25=0.78*0.565.6*(0.27+X+0.25)=0.078*5.60.52+X=0.078X=-0.442
=222×3×333+778×999=222×999+778×999=（222+778）×999=1000×999=999000
999×7.78＋333×6.66=999×7.78+333×(3×2.22)=999×7.78+999×2.22=999×(7.78+2.22)=999×10=9990
5.6*69.32+138.64*0.05+693.2*0.43=5.6*0.1*693.2+693.2*0.2*0.05+693.2*0.43=0.56*693.2+693.2*0.01+693.2
5.6*69.32+138.64*0.05+693.2*0.43=5.6*69.32+69.32*0.1+69.32*4.3=69.32*(5.6+0.1+4.3)=69.32*10=693.2
46.1×0.56＋5.38×5.6＋1×0.056＝46.1×0.56＋53.8×0.56＋0.1×0.56＝0.56×（46.1＋53.8＋0.1）＝0.56×100＝56
