1、列竖式计算
0.86×0.723.5×1.612.5×423.2×15
1.3×0.241.8×2.31.06×250.17×0.86
0.62×0.3927×0.43
2、脱式计算(能简算的要简算)
4.8×0.252.33×0.5×41.5×1051.2×2.5+0.8×2.5
50.4×1.9-1.83.76×0.25+25.81.08×0.8÷0.27
2.05÷0.82+33.644.28÷0.9÷4.19.07-22.78÷3.4
3、列竖式计算(除不尽的保留两位小数)

1.89÷0.547.1÷2.50.51÷0.22
1.3÷0.036.509÷0.270.68÷0.95
28.6÷1120.4÷243.64÷5.218.9÷2.7
6、解方程
x+0.3=1.83+x=5.4x-1.5=416-x=7.6
5x=1.5x÷1.1=315÷x=1.5
3x+6=182x-7.5=8.54x-3×9=29
7、解方程
2(x-2.6)=85(x+1.5)=17.58(x-6.2)=41.68x-3x=105
(x-3)÷2=7.513.2x+9x=33.35.4x+x=12.8
x-0.36x=1613(x+5)=1693.4x-48=26.8
