40.5/0.81-4.8*0.5=45×0.9/(9×0.9)-4.8×1/2=5-2.4=2.6
40.2÷0.048×8.1×4.8÷0.81=40.2×(4.8÷0.048)×(8.1÷0.81)=40.2×100×10=402×100=40200

第一个式子就是直接的计算了,40.5除以0.81直接等于50,然后50乘以1.2为60.用80.3直接减60就是22.3了.至于第二个式子:也是如此:1.2乘以4为4.8,然后是26.8-4.8为22
6.1÷0.2=30.540.5-30.5=1010×0.3=33-2.1=0.9
40.5/0.81*0.18=40.5/(0.405*2)*0.18=40.5/(40.5*0.02)*0.18=0.18/0.02=9
(0.81×0.75×0.48)÷(0.25×0.24×0.27)=(0.27×3×0.25×3×0.24×2)÷(0.25×0.24×0.27)=3×3×2=18
3.25×24=7816×15.5=248324÷40.5=840×0.25=1030÷12=2.555×0.8=444.6÷0.25=18.4
3.5+2.8=6.30.8÷0.001=80060÷50=1.239*0.77÷0.001=3003010-0.81=9.19

40.5/0.81-19.5=8010/81/2-19.5=100/2-19.5=50-19.5=30.5
0.81和0.27,7.5和0.25,0.48和0.24,除完后相乘,3*30*2=180再问:��ʽ再答:��0.81��0.27������7.5��0.25������0.48��0.24��=
