Question

0.75×11-23×0.25的简便计算怎么写？

Answer 1

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

Answer 2

把0.75拆分成0.25×3的积，转化出公因数，然后就可以用乘法分配律来进行简便计算了。
0.75×11-23×0.25
=0.25×3×11-23×0.25
=0.25×33-23×0.25
=0.25×(33-23)
=0.25×10
=2.5

Answer 3

原式=0.25*3*11-23*0.25=0.25*33-23*0.25=0.25*（33-23）=0.25*10=2.5

Answer 4

0.75×11-23×0.25的简便计算是：
0.25×33-23×0.25
=0.25×（33-23）
=0.25×10
=2.5

Answer 5

解
原式
=0.25×3×11-23×0.25
=0.25×(33-23)
=0.25×10
=2.5
乘法分配率
可以把0.75分成3个0.25 然后找出共同的乘数 进行计算 利用减法结合律和乘法分配律即可得出结果
