5-0.75/1.5*6.4=5-1/2*6.4=5-3.2=1.8
1.25*0.7*8*0.9=1.25*8*0.7*0.9=10*0.63=6.3
8.56*98+856*0.02==856*0.98+856*0.02=856
800*(0.3+1.25)/6.2=800*(1.24+0.31)/6.2=800*(0.2+0.05)=800*0.25=200
3.14*10.1-0.314=3.14*10=31.4
0.888*125*73=0.111*8*125*(8*9+1)=999*8+111
0.888*125*73+999*3=999*8+111+999*3=999*11+111=111*99+111

x除以1.5-1.25=0.75
1.25＋6.4＋0.75简便
小数乘法推广到小数 全对给50分!3.4×7×1.5 1.25+4.6+0.75 2.33×0.5×0.4×5 1.6×7.5×1.25= =

解方程x除于1.5-1.25=0.75 120-9x=1.2乘6.25是分开来的，
3/8比1/3=x比1/6 0.75/x=0.25/3 8/9比0.2=x比1.5 1/2比1/5=1/4比x 1.25比0.25=x/1.6
1.25+0.75*5得简便计算
