Question

4.65x32+2.5x46.5+0.465x430简便计算过程？

Answer 1

4.65x32＋2.5x46.5＋0.465x430
＝46.5x3.2＋46.5x2.5＋46.5x4.3
＝46.5x（3.2＋2.5＋4.3）
＝46.5x10
＝465

Answer 2

4.65x32+2.5x46.5+0.465x430
=4.65x32+25x4.65+4.65x43
=4.65x(32+25+43)
=4.65x100
=465

Answer 3

三段乘式中都出现了465这个数字只是小数点的位置不同可以简约成一样大的数4.65
也就是说可以变o换成这样的等式4.65x32＋25x4.65＋4.65×43＝4.65×（32十25＋43）＝4.65×100＝465。

Answer 4

原式=4.65×32+25×4.65+4.65×43=4.65×（32+25+42）=4.65×100=465

Answer 5

4.65×32+2.5×46.5+0.465×430
=(0.465×10)×32+(0.465×100)×2.5+0.465×430
=0.465×10×32+0.465×100×2.5+0.465×430
=0.465×320+0.465×250+0.465×430
=0.465×(320+250+430)
=0.465×(320+430+250)
=0.465×(750+250)
=0.465×1000
=465
