11.2除以9.6乘以2.4如何简便运算

11.2÷9.6x2.4 解:简便计算 =11.2÷2.4÷4x2.4 =11.2÷4 =2.8 祝天天向上。

题目打错了吧 应该是 9分之7吧 7/9÷11/6+2/9×6/11 =7/9×6/11+2/9×6/11 =6/11×(7/9+2/9) =6/11×1 =6/11 (含义是11分之6) 如果帮到你,请记得采纳,O(∩_∩)O谢谢

6.28x0.9=6.28x(1-0.1) =6.28-0.628 =5.652 3.14x11=3.14x(10+1) =31.4+3.14 =34.54 9.42x2.4=9.42x(2+0.4) =18.84+3.768 =22.608

因为此数加3以后,能被7,9整除,除以11余57×9=63,63÷11=5….8,8×2=16,除以11余5,最小可能是:63×2-3=123.故答案为:123.

9/11×( 11/9 )= 6×( 1/6 )=1.25×( 0.8 )=1

123 11+7d1=15+9d2=13+11d3 化简后得7d1-2=9d2+2=11d3 用d3=1,2,3,4...一一试 默认的d1,d2,d3都是整数

33.3×18.2+66.6×11.2-99.9×0.2 =33.3×18.2+33.3×2×11.2-33.3×3×0.2 =33.3×(18.2+22.4-0.6) =33.3×40 =1332

4/5减1/4的差乘十一分之六的积除以二十分之九能简便运算吗 (4/5-1/4)*6/11÷9/20 =11/20*6/11*20/9 =2/3 直接计算

2-(6/11)/(9/22)-2/3=2-6/11*(22/9)-2/3=2-4/3-2/3=2-(4/3+2/3)=2-2=0

9*(60.4+37.6)=9*98
