0.75×11-23×0.25的简便计算怎么写？

Answer 1

0.75×11转换成0.25×3×11，再提取共项0.25简便计算
0.75×11-23×0.25
=0.25×3×11—23×0.25
=0.25×（3×11—23） 提取共项0.25
=0.25×（33—23）
=0.25×10
=2.5
验算见截图

Answer 2

可以按照以下方式进行简便计算:
0.75×11-23×0.25
=0.25×3×11-0.25×23
=0.25×（3×11）-0.25×23
=0.25×（33-23）
=0.25×10
=2.5

Answer 3

可以把0.75分解成0.25*3
.，然后利用乘法分配率的逆运算来实现简算:
0.75×11-23×0.25
=0.25×3×11-0.25×23
=0.25×33-0.25×23
=0.25×（33-23）
=0.25×10
=2.5

Answer 4

0.75=0.25*3，因此，原式=0.25*33-0.25*23=0.25*(33-23)=0.25*10=2.5

Answer 5

0.75×11-23×0.25
＝0.25×3×11-23×0.25
＝0.25×(3×11-23)
＝0.25×(33-23)
＝0.25×10
＝2.5
