2.5-2.5×0.6-0.5的简便托市计算怎么算？

Answer 1

2.5－2.5×0.6－0.5
＝2.5×1－2.5×0.6－0.5
＝2.5×（1－0.6）－0.5
＝2.5×0.4－0.5
＝1－0.5
＝0.5

Answer 2

=2.5×1－2.5×0.6－2.5×0.2
=2.5×(1－0.6－0.2)
=2.5×0.2
=0.5

Answer 3

2.5-2.5Ⅹ0.6-0.5简便计算可立式：
2.5X(1-0.6)一0.5
=2.5X0.4-0.5
=1-0.5
=0.5
希望能够帮到你。

Answer 4

2.5-2.5x0.6-0.5
=2.5x（1-0.6）-0.5
=2.5x0.4-0.5
=1-0.5
=0.5

Answer 5

2.5-2.5*0.6-0.5
=2.5*（1-0.6）-0.5
=2.5*0.4-0.5
=1-0.5
