2.6乘1.9除以2.6能简便计算吗

可以 2.6÷2.6×1.9=1.9

2.6÷2.6*1.9x1.9=1.9x1.9=3.61

答:9/25÷6+1÷6*6/25=1/10=0.1

6.9 1.9×0.2÷7.6的简便运算 6.9 1.9×0.2÷7.6 =6.9+0.2÷4 =6.9+0.05 =6.95

解: (9.1+2.6)÷1.3 =11.7÷1.3 =9

5/9-(2/9+1/6)=5/9-2/9-1/6=3/9-1/6=1/3-1/6=2/6-1/6=1/6

12.6*7.6*2.32/1.9*1.4*2.9

2/3*6+2/3*9=4+6=10

括号2/9加1/6夸完除以7/2简便计算 解: (2/9+1/6)÷7/2 =(4/18+3/18)×2/7 =7/18×2/7 =1/9

7.6*1.9-96.2÷7.4 =7.6*(2-0.1)-13 =15.2-13-0.76 =2.2-0.76 =1.44
