巧算:0.1+0.2+0.3+0.4+0.5+0.6+0.7+0.8+0.9
0.1+0.1+0.3+0.4+.+0.8+0.9+1=?简算
0.4,0.8,1.6,3.2
0.8:0.4的比值
0.8×0.25×0.4×12.5
1.25×0.4= 1×3.12-0.8= 5.4×0.2-0.9= 1.25×0.4=
判断题:0.8+0.8+0.8+0.4+0.4=0.8*4=0.4*8
(0.1*0.3*0.9+0.2*0.6*1.8+0.3*0.9*2.9)除以(0.1*0.2*0.4+0.2*0.4*0.8+0.3*0.6*1.2)
(0.1*0.3*0.9+0.2*0.6*1.8+0.3*0.9*2.9)除以(0.1*0.2*0.4+0.2*0.4*0.8+0.3*0.6*1.2)
0.8*25*1.25*0.4(简算)
(1.9×0.8+0.48)/0.4
0.4/1.25=0.8/x
0.8:0.4=x:0.
怎样简便怎样计算.0.9×10.1 0.8×(12.5–1.25)怎样简便怎样计算.0.9×10.1 0.8×(12.5–1.25) 7.6×0.4–0.4×5.1
0.1×0.2×0.4+0.2×0.4×0.8+0.3×0.6×1.2)分之(0.1×0.3×0.9+0.2×0.6×0.8+0.3×0.9×2.7)
(0.1×0.2×0.4+0.2×0.4×0.8+0.3×0.6×1.2)分之(0.1×0.3×0.9+0.2×0.6×0.8+0.3×0.9×2.7)=
0.4×0.4×0.4=0.8×0.25x 怎么解
