Question

9.6×37+4.8×2.6的简便计算是什么？

Answer 1

题出错了
应该是9.6×3.7+4.8×2.6
=4.8×2×3.7+4.8×2.6
=(2×3.7+2.6)×4.8
=(7.4+2.6)×4.8
=10×4.8
=48

Answer 2

从题中我们可以看出9.6是4.8的两倍
那就把9.6写成4.8×2
4.8×2×37+4.8×2.6
=(2×37+2.6)×4.8
=(74+2.6)×4.8
=76.6×4.8
=367.68

Answer 3

9.6*37+4.8*2.6＝4.8*2*37+4.8*2.6＝4.8*（74+2.6）＝4.8*76.6＝（5-0.2）（76+0.6）＝5*76+5*0.6-0.2*
76-0.2*0.6＝380+3-15.2-0.12＝383-15.22=367.78

Answer 4

9.6×37+4.8×2.6
=4.8×2×37+4.8×2.6
=4.8×74+4.8×2.6
=4.8×（74+2.6）
=4.8×76.6
=6×0.8×76.6
=6×76.6×0.8
=2×3×76.6×0.8
=2×76.6×3×0.8
=153.2×3×0.8
=459.6×0.8
=367.68

Answer 5

9.6跟4.8是2倍的关系，
4.8*2*37+4.8*2.6
4.8*(2*37+2.6)
4.8*76.6
这里没什么好的算法，只能去凑数，方便口算
(5-0.2)*76.6
383-15.32=367.68
