用简便方法计算.0.42×160+36×1.6-68×1.6 32×0.25×12.5×0.2×5 0.92×54+0.46×92
0.42×160+36×1.6-68×1.6 =1.6x(42+36-68) =1.6x10 =16 32×0.25×12.5×0.2×5 =4x8x0.25x12.5x0.2x5 =(4x0.25)x(8x12.5)x(5x0.2) =1x100x1 =100 0.92×54+0.46×92 =92x0.54+96x0.46 =92x(0.54+0.46) =92x1 =92
用简便方法计算.0.42×160+36×1.6-68×1.6 32×0.25×12.5×0.2×5 0.92×54+0.
用简便方法计算:100.01*2.7= 0.42*160+36*1.6-34*3.2= 32*0.25*12.5*0.2
