Question

0.75×11-23×0.25的简便计算怎么写？

Answer 1

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

Answer 2

0.75X11-23x0.25
=0.25x3x11-23x0.25
=0.25x33-23x0.25
=｛33+（-23）｝*0.25
=｛33-23｝*0.25
=10*0.25
=2.5

追答

0.75X11-23x0.25=0.25x3x11-23x0.25=0.25x33-23x0.25=｛33+（-23）｝*0.25=｛33-23｝*0.25=10*0.25=2.5

0.75X11-23x0.25=0.25x3x11-23x0.25=0.25x33-23x0.25=｛33+（-23）｝*0.25=｛33-23｝*0.25=10*0.25=2.5

0.75X11-23x0.25=0.25x3x11-23x0.25=0.25x33-23x0.25=｛33+（-23）｝*0.25=｛33-23｝*0.25=10*0.25=2.5

Answer 3

0.75*11-23*0.25
=0.25*3*11-23*0.25
=0.25*（33-23）
=0.25*10
=2.5
这是最简便的方法

Answer 4

解:根据题意:0.25(3x11-23)=0.25×10
=2.5
所以简便计算结果为2.5

Answer 5

0.75×11-23×（1-0.75）
0.75×11+23×0.75-23
0.75×（11+23）-23
0.75×34-23
0.75×30+0.75×4-23
22.5+3-23
2.5
