1.8除以0.5的脱式计算怎么简算

解:1.8/0.5 =(1.8*2)/(0.5*2) =3.6/1 =3.6

6.8÷0.5 =68÷5 =13.6

17.5÷0.5X1.8 =35x1.8 =63 , 你好,本题已解答,如果满意 请点右下角“采纳答案”。

105*0/5 =0/5 =0 0与任何相乘都得0 0除以任何数都得0。

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

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

(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

(1)0.8×0.25×4×0.5=(0.8×0.5)×(4×0.25)=0.4×1=0.4;(2)4.6×[3÷(1.45-1.05)]=4.6×[3÷0.4]=4.6×7.5=34.5;(3)55×9.9=55×(10-0.1)=55×10-55×0.1=550-5.5=544.5;(4)4.87×2.34+4.87×7.66=4.87×(2.34+7.66)=4.87×10=48.7.

5.4除以0.125脱式计算用简便方法 =(5.4x8)÷(0.125x8) =43.2÷1 =43.2
