29.5*1.6+1.95*16怎样简便计算?
29.5*1.6+1.95*16
=2.95*16+1.95*16
=(2.95+1.95)*16
=[(3-0.05)+(2-0.05)]*16
=(5-0.1)*16
=5*16-0.1*16
=80-1.6
=78.4

29.5*1.6+1.95*16
=1.6×﹙29.5＋19.5﹚
=1.6×49
=78.4

29.5*1.6+1.95*16
=2.95*16+1.95*16
=(2.95+1.95)*16
=4.9*16
=78.4

29.5*1.6+1.95*16=2.95*16+1.95*16=16*（2.95+1.95）=16*3.9=16*（4-0.1）=64-1.6=62.4

23.4乘1.6减34乘0.16 =23.4*1.6-34*0.16 =234*0.16-34*0.16 =(234-34)*0.16 =200*0.16 =32 23.4*1.6-34*0.16 =23.4*
