12.6×7.6×2.32÷1.9÷1.4÷2.9的简便算法

原式=(12.6÷1.4)×(7.6÷1.9)×(2.32÷2.9) =9×4×0.8 =36×0.8 =28.8 望采纳,谢谢

原式 =(12.6÷1.4)x(7.6÷1.9)x(2.32÷2.9) =9x4x0.8 =36x0.8 =28.8 供参考。

=12.6/1.4*(7.6/1.9)*(2.32/2.9) =9*4*0.8 =36*0.8 =144/5=28.8

12.6÷2.8 3.2×1.4的简便算法 12.6÷2.8 3.2×1.4 =4.5+4.48 =8.98 直接计算 没有简算

18.9-18.9÷1.4 =18.9-13.5 =5.4 , 你好,本题已解答,如果满意 请点右下角“采纳答案”。

0.42ⅹ2/0.7x2x12.6=0.6Ⅹ12.6=7.56

9.4÷【[1.3+1.4]÷0.27】 =9.4÷【2.7÷0.27】 =9.4÷10 =0.94

原式 =18.9×2-18.9×5/7 =18.9×(2-5/7) =18.9×9/7 =2.7×9 =24.3
