0.08乘0.5加8.4除以0.6的脱式计算: 解: 0.08x0.5+8.4÷0.6 =0.4+14 =14.4

450÷18÷5 =25➗5 =5

0.15乘以0.2除以0.5的脱式计算怎么算 =0.15x0.2/(1/2) =0.15x2x0.2 =0.3x0.2 =0.06

(1)1.8×2.58+0.5+1.42×1.8=1.8×(2.58+0.5+1.42)=1.8×4.5=8.1(2)(54.7-17.5)×(0.45÷0.9)=37.2×0.5=18.6(3)52.91-311113-18213=52.91-(311113+18213)=52.91-50=2.91(4)15-8811+212=(15-8+2)-(811-12)=9-522=81722

(8.1÷0.4+0.5)×0.6 =(8÷0.4+0.1÷0.4+0.5)×0.6 =(20+0.25+0.5)×0.6 =20×0.6+0.25×0.6+0.5×0.6 =12+0.15+0.3 =12.45

2.5x0.6一1.8X0.5 =2.5×0.6-0.6×1.5 =0.6×(2.5-1.5) =0.6
