(1)102m-n(10m)210n=0.01,∵10-2=0.01,∴2m-n=-2;(2)9m÷3n=32m-n=3-2=19.
0.0324再问:几题再答:0.03240.00972再答:2562.5再答:0.18750.09375
10根0.2-2根0.5+4根0.125=12根1/5-2根1/2+4根1/8=(12根5)/5-根2+根2=(12根5)/5.
3/10:3/5=1/4:0.5
41.20.360.108()()规律:后一个数为前一个乘0.3:41.20.360.108(0.0324)(0.00972)1.6410()()156.25规律:后一个数为前一个除以0.4:1.64
解题思路:(1)4×0.3=1.2,1.2×0.3=0.36,0.36×0.3=0.0324,0.0324×0.3=0.00972。连续×0.3(2)连续乘2.5。解题过程:(1)4,1.2,0.36
(1)0.108×0.3=0.0324,0.0324×0.3=0.00972;(2)10×2.5=25,25×2.5=62.5;(3)0.375×0.5=0.1875,0.1875×0.5=0.093
0.36×0.8÷0.6=X0.288÷0.6=XX=0.48这个书上例题有哦而且还不是6下的是6上的吧
3.6X0.2=0.36X2很容易看出来原式可以写成0.36X(98+2)=0.36X100=36
依次乘以0.30.03040.00972依次乘以2.52562.5
0.36:X=1/10:4/90.36×4/9=1/10x1/10x=0.16x=1.6
4/5X=25x2.8X=87.5再答:1.2X=75x0.7x=43.75再问:还有一个再答:1/10X=0.36x4/9X=1.6再答:送个物品给我嘛?再答:送个物品给我嘛?再问:什么物品再答:1
(1)2/5X-4=0.362/5X=4.36X=4.36*5/2X=10.9(2)20%X-0.2=2420%X=24.2X=24.2/20%X=121(3)(X-10)*2+70=250(X-10
1.25×0.2+0.36×0.2=0.25+0.072=0.322
=-9=-30=0
0.2分之0.1x+0.05-0.5分之0.2x-0.05+5/4=05(0.1x+0.05)-2(0.2x-0.05)+1.25=00.5x+0.25-0.4x+0.1+1.25=00.1x+1.6
X-(0.2X+10)-1.2*(0.2X+10)+8=0.36X0.64X-(0.2X+10)(1+1.2)+8=00.64X-0.44X-22+8=00.2X-14=0X=70
4,1.2,0.36,0.108依次乘以0.3则0.108x0.3=0.0324希望对你有帮助,满意请及时采纳,你的采纳是我回答的动力!
