9.6%7.6×1.1用简便计算怎么算

9.6-7.6×1.1 =9.6-7.6x(1十0.1) =9.6-7.6-0.76 =2-0.76 =1.24

解:根据提取公因式的简便方法, 原式=4/7x6/9+4/7x1/9 =4/7x(6/9+1/9) =4/7x7/9 =4/9

76×1.9+7.6×81的简便算法 76×1.9+7.6×81 =7.6*19+7.6*81 =7.6*(19+81) =7.6*100 =760

7.6*9.9=7.6(10.-0.1)=7.6*10-7.6*0.1=76-0.76=75.24

请采纳

=9.09+7.8 =16.87

6.7×9.9=6.7×(10-0.1)=67-0.67=66.33

7.6*9.9-7.6 =7.6*9.9-7.6*1 =7.6*(9.9-1) =7.6*8.9 =67.64

8.9+1.1乘以15.6+6.7 =10X(15.6+6.7) =10X15.6+10X6.7 =156+67 =223
