3.25乘0.87加0.325乘8.7简便计算

3.25乘五点7+0点325×33加3.25的简便算法 3.25乘五点7+0点325×33加3.25 =3.25*(5.7+3.3+1) =3.25*10 =32.5

3.25*0.8+0.325 =3.25x(1-0.2)+0.325 =3.25-3.25x0.2+0.325 =3.25-0.65+0.325 =2.6+0.325 =2.925

3.25/100=0.0325,记得换算时除以100就好了

3.25-3.25×0.9 =3.25×(1-0.9) =3.25×0.1 =0.325

3.25×0.9+0.325 =0.325x9+0.325 =0.325x(9+1) =0.325x10 =3.25

原式=(0.325*2)➗(2.5*2)+3.97=0.65/5+3.97=0.13+3.97=4.1 18.4+4.3x2.8=18.4+4.3*(2+0.8)=18.4+8.6+3.44=27+3.44=30.44

325乘0.25+4.35乘2.5+ 0.045乘25 =32.5x2.5+4.35x2.5+0.45x2.5 =(32.5+4.35+0.45)x2.5 =37.3x2.5 =(30+7+0.3)x2.5 =30x2.5+7x2.5+0.3x2.5 =75+17.5+0.75 =93.25

0.325×101-0.325=0.325×(101-1)=0.325×100=32.5 101个0.325减去1个0.325等于100个0.325

(0.225+0.325)/2 =0.55/2 =0.275

325×0.36+6.75x36 =3.25×36+6.75x36 =36*(3.25+6.75) =360
