=(12×8__)÷(1.25×8__)=(96)÷(10)=(9.6)94÷0.25÷4=94÷(_0.25_×_4_)=94÷(1)=(94)主要是利用乘法原理及0.25*4=1,1.25*8=1
0.25×4÷0.25×4=0,25÷0.25X4X4=1X4X4=16
0.25+0.04÷0.5=0.25+0.08=0.33(0.25+0.04)÷0.35=0.31÷0.35=31/35
94÷0.25÷4=94÷(0.25×4)=94÷(1)=(94)这是利用除法商不变的性质.过程应该是这样的(94×4)÷(0.25×4)÷4=94÷(0.25×4)×4÷4=94÷(0.25×4)
1÷0.25=47.9÷0.01=790(2.5+0.9)×0.4=1.36(1.5+0.25)×4=7
【1】8.8÷0.25=8.8x4÷(0.25x4)=35.2÷1=35.2【2】999.9+99.9+9.9+0.9+0.4=999.9+0.1+99.9+0.1+9.9+0.1+0.9+0.1=1
13.6÷0.25=(13.6×4)÷(0.25×4)=54.4÷1=54.5
2.4÷0.25=2.4/1*4=9.6
0.25*0.4=2/5(x-20)x-20=0.25x=20.25
(7.4+2.6)x2.5÷0.4=62.5再答:��7.4��2.6����2.5��0..4��16.25再问:̫����再问:лл��лл再答:������
{[6/3÷(-0.25)+(-0.4)×(-25/4)]÷1.25-10}×0.3=-2.52
先算10.56+9.44=20,再算3.75-1.75=2,所以原式=10.56+9.44+3.75-1.75=20+2=22望采纳!
1.0.4÷0.25=0.4×4=1.62.(0.78+0.65)÷0.13=0.78÷0.13+0.65÷0.13=6+5=113.客车1.5小时行60千米,面包车的速度是客车的1.25倍,面包车每
6.4×0.25+3.6÷4=6.4×0.25+3.6×0.25=(6.4+3.6)×0.25=10×0.25=2.5
[(5.84-3.9)÷0.4+0.15]×0.92=[1.94÷0.4+0.15]×0.92=[4.85+0.15]×0.92=5×0.92=4.6
6*(0.25/0.25)*6=6*1*6=36
4×0.5×0.25=(4×0.25)×0.5=1×0.5=0.50.4×16×0.25=(0.4×0.25)×16=0.1×16=1.60.35×99-0.35×9=0.35×(99-9)=0.35
2/5再答:应该是4/25再问:比的应用6分之5÷0.3=几分之几再问:比的应用6分之5÷3分之4=几分之几再答:第一个答案和笫二个都错了是8/5再问:比的应用6分之5÷3分之4=几分之几再问:还有1
