0.8x6 (x%6)=8.8

40x6+40x0.75x=40x0.8(x+6) 6+0.75x=0.8(x+6) 6+0.75x=0.8x+4.8 0.8x-0.75x=6-4.8 0.05x=1.2 x=24

3.2x一0.8X6.5=9.2 解:3.2×-5.2=9.2 3.2×=9.2+5.2 3.2×=14.4 ×=14.4÷3.2 ×=4.5

7.8×1.001×6.28÷(18.2×0.26×0.125) =7.8×1.001×6.28÷18.2÷0.26÷0.125 =(7.8÷0.26)×6.28×(1.001÷18.2)×8 =【(7.8÷0.13)÷(0.26÷0.13)】×【(1.001÷0.007÷13)÷(18.2÷0.007÷13)】×(6.28×8) =(60÷2)×(11÷200)×6.28×8 =30×8÷200×11×...

(6.5x0.8+9.2x6.5)÷6.5+0.5的简便计算。 =(0.8+9.2)x6.5÷6.5+0.5 =10+0.5 =10.5

-6.08*(5.4+0.1)+4.5*(7-0.2) =6.08*5+6.08*0.5+31.5-9 =30.4+3.04+22.5 =55.94

6.7x943+6.8x67-67x0.1 =67x94.3+6.8x67-67x0.1 =67x(94.3+6.8-0.1) =67x(100+1) =67x100+67x1 =6700+67 =6767

125x6.8x0.04 =(125x0.04x2)x3.4 =10x3.4 =34 如有帮助请采纳, 如对本题有疑问可追问,Good luck!

1.5x4/5+0.8x6.5+4x2/5简便计算 1.5x4/5+0.8x6.5+4x2/5 =1.5*4/5+6.5*4/5+2*4/5 =4/5*(1.5+6.5+2) =4/5*10 =8
