(13 X 0.58-4.87+0.42 X 13- 5.13) X 4.25
计算下列各题 0.5 X 1.6+0.5 X 26.4
2.009×43+20.09×2.9+200.9×0.28
我会脱式计算。(能简算的要简算) 2.12×0.8×5 54.5-7.2×3.5 0.65×101
竖式计算我最行。(带※得数保留一位小数)0.83×3.2= ※2.7×5.1≈ 1.5×0.45=
1.8×2.4- 1.8×0.24= 180×2.4= 180×0.24= 0.18×0.24= 0.18×0.24=
325×0.36+6.75×36
5.6×0.375+×5.4-0.375×0.9
12.5×16×3.8
4935÷47+5.4×8.5
0.56×=
11.75- 1.7=
3.6×0.25×4=
0.64÷0.08=
