99x0.33+0.33(
99X0.33 0.33 -
=（99+1）x0.33 =100x0.33 =33 希望能帮到你！
99×0.33+0.33题中公因数是0.33，我可以提取公因数后就变成：99×0.33+0.33 =0.33×（99+1）0.33×100 =33
=（99+1）x0.33 =100x0.33 =33 希望能帮到你！

0.33X99用筒便方法计算 -
0.33x（100—1）0.33x100—0.33x1 33—0.33 32.67
99×0.33+0.35 把他看做100个0.33，之后再减去1个0.33就OK了。100*0.33-0.33+0.35=(100-1)*0.33+0.35 =33+0.02 =33.02
0.99X33简便方法? -
可以把0.99换成1-0.01，然后再跟33相乘就可以了。（1-0.01）x33=33x1-33x0.01=33-0.33=32.67
999×0.33+333×0.66 =999×0.33+333×3×0.22 =999×0.33+999×0.22 =999×(0.33+0.22)=999×0.55 =(1000-1)×0.55 =1000×0.55-1×0.55 =550-0.55 =549.45
97×0.33简便运算? -
97x0.33简便运算：97x0.33 =（100-3）x0.33 =33-0.99 =33-1+0.01 =32+0.01 =32.01
0.33*9.9+0.033 =0.33*9.9+0.33*0.1 =0.33*(9.9+0.1)=0.33*10=3.3
