要过程

Answer 1

1：
2：原式＝0.483*5.9-0.324*5.9+0.41*1.59
＝（0.483-0.324）*5.9+0.41*1.59
＝0.159*5.9+0.41*1.59
＝1.59*0.59+0.41*1.59
＝（0.59+0.41）*1.59
＝1.59
3：原式=2.375*39.87+6.832*39.87+6.013*92.07
=（2.375+6.832）*39.87+6.013*92.07
=9.207*39.87+6.013*92.07
=92.07*3.987+6.013*92.07
=（3.987+6.013）*92.07
=920.7

5：原式＝134*3.3-240*0.12+（134+24）*6.7
=134*3.3+134*6.7+24*6.7-240*0.12
=134*（3.3+6.7）+240*0.67-240*0.12
=1340+240*（0.67-0.12）
=1340+240*0.55
=1470
我没时间了 只能答这些了 下次吧
