Question

3.5×0.54-0.35+0.35×5.6用简便方法怎么做？

Answer 1

3.5×0.54-0.35+0.35×5.6
=0.35×10×0.54-0.35+0.35×5.6
=0.35×5.4-0.35+0.35×5.6
=0.35×（5.4-1+5.6）
=0.35×10
=3.5

Answer 2

解，原式=0.35x10x0.54-0.35x1+0.35x5.6
=0.35x(10x0.54-1+5.6)
=0.35x10
=3.5

Answer 3

这道题你可以利用积不变的规律以及乘法分配律进行简便计算。
3.5X0.54-0.35+0.35X5.6
=0.35X5.4-0.35+0.35X5.6
=0.35X（5.4-1+5.6）
=0.35X（4.4+5.6）
=0.35X10
=3.5

Answer 4

3.5x0.54－0.35＋0.35x5.6
＝0.35x5.4－0.35x1＋0.35x5.6
＝0.35x（5.4一1＋5.6）
＝0.35x10
＝3.5

Answer 5

3.5x0.54-0.35+0.35x5.6
=(3.5/10)x(0.54x10)-0.35+0.35x5.6
=0.35x5.4-0.35+0.35x5.6
=0.35x(5.4-1+5.6)
=0.35x10
=3.5
