0.13+0.23+0.33+…+0.93.
计算:(0.12+0.22+0.32+0.42+0.52)/(0.13+0.23+0.33+0.43)=?
0.3+0.5+0.7+0.9+0.11+0.13+…+0.99.
(1) (-4½)-{3 2/5 -[(0.13)-(0.33)]}
四则运算0.04*0.13+0.04*0.17+0.26*(0.38*0.1+0.62*0.13)+0.3*(0.23*
0.1+0.3+0.5+0.7+0.9+0.11+0.13+…+0.99=______.
计算:0.1+0.3+0.5+0.7+0.9+0.11+0.13+0.15+…+0.97+0.99.
5.98除以0.23 列竖式……
