0.61乘以99的简便计算

简便计算:0.64*100=6464-0.64=63.36 希望能帮到你

0.96x99=0.96x(100-1)=96-0.96=95.04 如有帮助请采纳,如对本题有疑问可追问,Good luck!

5.95*99=(6-0.05)*(100-1)=600-5-6+0.05=589+0.05=589.05 再看看别人怎么说的.

2.73*99=2.73*(100-1)=2.73*100-2.73=273-2.73=270.27

0.76*99=0.76*(100-1)=76-0.76=75.24

=61*(100-1) =6100-61 =6049

六十七减去六十七乘以百分之九十九=67x(1-0.99)=67x0.01=0.67

99*0.84+0.84=(99+1)*0.84=100*0.84=84

99*8.08=(100-1)*8.08=100*8.08-1*8.08=808-8.08=799.92

这道题目是用乘法速算法计算的.46*99=46*(100-1)=46*100-46=4600-46=4554.
