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”。

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

(1)2.25×1.8+12.5×0.18=(2.25+1.25)×1.8=4×1.8=7.2;(2)7.28-(1.28+0.25)=7.28-1.28-0.25=6-0.25=5.75;(3)2÷85×2524=2×58×2524=12596;(4)[1-(13-14)]×24=1×24-(13×24-14×24)=24-(8-6)=24-2=22;(5)3.68-0.82-0.18=3.68-(...

(1)1.8×5.46+1.8×4.54=1.8×(5.46+4.54)=1.8×10=18;(2)4×0.8×12.5×2.5=4×2.5×0.8×12.5=(4×2.5)×(0.8×12.5)=10×10=100;(3)9.07-22.78÷3.4=9.07-6.7=2.37.

240

5.64÷0.4+0.6×1.8 =14.1+1.08 =15.18

2.08×60 =2*60+0.08*60 =120+4.8 =124.8 ,2.5×0.6-1.8×0.5 =1.5-0.9 =0.6
