Question

26.3×46+2.63×640简便方法怎么做？

Answer 1

26.3×46+2.6×640＝26.3×46+26.3×64＝26.3×（46+64）＝26.3×110＝2893。这道题作用了第一个因数扩大的倍数和第二个因数缩小的倍数相同，乘积不变，还有乘法结合律。

Answer 2

26.3×46+2.63×640简便方法这么做：
26.3×46+2.63×640
=26.3×46+26.3×64
=26.3×(46+64)
=26.3×110
=2893

Answer 3

2.63*10*46+2.63*640=2.63*（460+640）=2.63*（1000+100）=2.63*1000+2.63*100=2630+263=2893希望帮到你，望采纳，谢谢！

Answer 4

简便计算为
26.3*46+2.63*640
=26.3*46+26.3*64
=26.3*（46+64）
=26.3*100+26.3*10
=2630+263
=2893

Answer 5

26.3×46+2.63×640
=2.63×460+2.63×640
=2.63×(460+640)
=2.63×1000
=2630
