45x40x125的简便运算
0.47x40x125简便计算? -
0.47x40x125 =0.47x(40x125)0.47x500 =0.47x(100x5)=0.47x100x5 =47x5 =235
56x40x125 =(56x5)x(8x125)=280x1000 =280000
0.47x40x125 =0.47x(40x125)0.47x500 =0.47x(100x5)=0.47x100x5 =47x5 =235
56x40x125 =(56x5)x(8x125)=280x1000 =280000
=280000
125x14x40 =125*8*5*14 =1000*70 =70000

25X40X4X125用简便计算怎么做=25x4x5x8x125 =100x5x1000 =500000
102乘以45的简便计算方法如下:102*45=(100+2)*45=100*45+2*45=4500+90=4590 这个方法运用了乘法的结合律和分配律,只要熟练掌握乘法、加法、减法、除法的各种运算法则,就能快速、准确地算出答案。
(25x125)×(8x40) -
简便计算过程方法如下解:25x125)×(8x40)=25×125×8×40 =(25×40)×(125×8)1000×1000 =1000000
解:125x16x40等于(80000 )∵已知需求出125x16x40等于多少∴方法一125 x 16 x 40 = 125 × 16 × (5 × 8) 125 × 16 × 5 × 8 = (125 × 8)× (16 × 5) 1000 × 80 = 80000 方法二125 x 16 x 40 = 125 × (2 × 8)× 40 = 125 × 2 × 8 等会说。
8x5X125X40用脱式计算用简便运算 -
5和40结合起来,都分别给她们添上一个括号,就是式子(8×125)×(5×40),现在在按照四则混合运算的顺序进行计算,1000×200=200000,用运算定律,可以使计算更加简,具体书写请看下图,希望我的回答能够帮助到您的,祝你学习进步,心想事成,万事如意,敬请采纳,谢谢!
可以这样简便计算:125x13x5x8=125x8x(13x5)1000x65=65000
