12.5x0.32x0.25简箅

0.32x12.5x0.25=0.4*0.8*12.5*0.25=(0.4*0.25)*(0.8*12.5)=0.1*10=1

=12.5*0.8*0.4*0.25=(12.5*0.8)*(0.4*0.25)=10*0.1=1

0.125x0.32x0.25=0.125x0.4x0.8x0.25=(0.125x0.8)x(0.25x0.4)=0.1x0.1=0.01 ,你好,本题已解答,如果满意 请点右下角“采纳答案”.

12.5X0.64X0.25=(12.5X4)X(0.25X4)X0.04 =50X1X0.04=2

0.25x0.32x12.5=0.25*4*0.8*12.5=1*10=10

12.5*0.32*2.5=(12.5*0.8)*(0.4*2.5)=1*1=1

12.5x0.32x1.25=12.5x(0.4x0.8)x1.25=(12.5x0.4)x(0.8x1.25)=5x1=5

(12.5+0.25)*0.32=(12.5+0.25)*0.08*4 这样可以了吧 自己还是要多思考的

0.125X0.32X0.25简变运算=0.125x0.8x0.4x0.25=(0.125x0.8)x(0.4x0.25)=0.1x0.1=0.01

12.5*0.96*0.25=12.5*0.08 *4*0.25*3=1*1*3=3
