10.1 5.5的简便运算

5.5/9.9=(5.5/1.1)/(9.9/1.1) =5/9

=(10+0.1)乘以55 =10乘以55+0.1乘以55 =550+5.5 =555.5

10.1x55简便算法10.1x55=55*(10+0.1)=55*10+55*0.1=550+5.5=555.5

5.5*10.1=5.5*(10+0.1)=5.5*10+5.5*0.1=55+0.55=55.55你好,本题以解答,如果满意,请点右上角“采纳答案”,支持一下.

这样

10.155简便运算=(10+0.1)x55=10x55+0.1x55=550+5.5=555.5

4.6x202+10.1x5.5 =4.6x101x2+10.1x5.5 =4.6x10.1x10x2+10.1x5.5 =92x10.1+10.1x5.5 =(92+5.5)x10.1 =942.75 =(92+5.5)x10.1 =97.5*(10+0.1) =97.5*10+9.75 =984.75 上面错了,真不好意思哦

这个已经是够简算的了吧(10-5.5)x2=4.5x2=9(10-5.5)x2=10x2-5.5x2=20-11=9望采纳

=10 =10乘以5.5加0.1乘以5.5=55加0.55=55.55

问:5.5*10.2简便运算答:5.5*10.2=5.5*10+5.5*0.2=55+1.1=56.1答题完毕,谢谢采纳
