解樱仿:(95一脊好纤3.8)÷3.8
=95÷3.8-3.8÷3.8
=95*4÷(3.8*4)-3.8÷3.8
380÷3.8÷4-3.8÷3.8
=100÷4一1
=25-1
=24
45.2*4/(25x4)
=180.8/袜磨100
=1.808
0.17÷34
=0.17÷(17X2)
=0.17/17/2
=0.01/2
=0.005
=95÷3.8-3.8÷3.8
=95*4÷(3.8*4)-3.8÷3.8
380÷3.8÷4-3.8÷3.8
=100÷4一1
=25-1
=24
45.2*4/(25x4)
=180.8/袜磨100
=1.808
0.17÷34
=0.17÷(17X2)
=0.17/17/2
=0.01/2
=0.005
