①18.3×0.25+5.3÷0.4-7.13=4.575+13.25-7.13=17.825-7.13=10.695;②120043−2003×(20042+2005)=120042×2004−20
ls强人1.原式=78÷15x18=93.62.原式=0.25x4+0.25x0.4=1+0.1=1.13.原式=7+0.28+32/25=7+7/25+32/25=8又14/254.原式=67x(3
=(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
9.5×10.1=9.5×10+9.5×0.1=95+0.95=95.950.25×3.24×4=(0.25×4)×3.24=1×3.24=3.240.84×1.7÷0.07=0.84÷0.07×1.
1.77/77*29.08=29.082.100*0.79+0.79*1=79.793.91-10/(0.25*0.4)=91-10/0.1=-94.402-298*(2.5*0.4)*(12.5*8
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
