Question

35.7×89+35.7×12-35.7怎么简便计算？

Answer 1

根据题意，这道题用到的简便计算方法是乘法分配律和乘法结合律，原式=35.7*89+35.7*12-35.7*1=35.7*（89+12-1）=35.7*100=3570。

Answer 2

35.7×89+35.7×12-35.7

＝35.7×89+35.7×12-35.7×1

＝35.7×（89+12-1）

＝35.7×（89+11）

＝35.7×100

＝3570

Answer 3

这是小学数学乘法分配律的扩大运用进行简便计算的一种类型题。即:35.7ⅹ89+35.7ⅹ12-35.7=35.7x（89+12-1）=35.7ⅹ100=3570

Answer 4

35.7×89+35.7×12-35.7=35.7×89+35.7×12-35.7×1=35.7×（89+12-1）=35.7×100=3570

Answer 5

35.7x89+35.7x12-35.7=35.7x89+35.7x12-35.7x1=35.7x（89+12-1）=35.7x100=3570
