65.4×0.67+6.54×3.1

65.4*0.67+6.54*3.1+0.654*2=6.54*(6.7+3.1+0.2)=6.54*10=65.4

65.4*0.67+6.54*3.1+.-0.654*2 =65.4*0.67+65.4*0.31+65.4*0.02 =65.4*(0.67+0.31+0.02) =65.4*1 =65.4

65.4*0.67+6.54*3.1+0.654*2 =65.4*0.67+65.4*0.31+65.4*0.02 =65.4*(0.67+0.31+0.02) =65.4*1 =65.4

原式=6.54*6.7+6.54*3.1+6.54*0.2 =6.54*(6.7+3.1+0.2)=6.54*10=65.4

原式=65.4*0.67+65.4*0.31+65.4*0.02=65.4*(0.67+0.31+0.02)=65.4*1=65.4.

65.4x0.67+6.54x3.1+0.654x2=0.654x67+0.654x31+0.654x2=0.654x(67+31+2)=0.654x100=65.4 如还不明白,请继续追问.如果你认可我的回答,请及时点击【采纳为满意回答】按钮 手机提问的朋友在客户端右上角评价点【满意】即可.

65.4x0.67+6.54x3.1+0.654x2=65.4x(0.67+0.31+0.02)=65.4x1=65.4

巧算下面这道题:65.4x0.67+6.54x3.1+0.654x2=6.54x6.7+6.54x3.1+6.54x0.2=6.54x(6.7+3.1+0.2)=6.54x10=65.4

解:65.4X0.67十6.54X3.1十0.654X2 =6.54x6.7+6.54x3.1+6.54+20 =6.54x(6.7+3.1+20) =6.54x30.4 =6.54x(30+0.4) =6.54x30+6.54x0.4 =196.2+2.616 =198.816

6.54+1.366.45+7.64=(6.54-6.45)+(1.36+7.64)=0.09+9=9.09
