✔ 最佳答案
[4除以(1+33又3分之1%)]*(12x10)x(1-90%) [4/(1+100/3%)](12x10)(1-90%)...............33又3分之1=100/3
=[4/(1+1/3)](120)(1/10)............1%=1/100
=[4/(4/3)](12)
=[4(3/4)](12)
=36

[4/(1+33又3分之1%)]*(12x10)x(1-90%)
= {4/(1+ (100/3) *(1/100)}*(120)x(0.1)
= [4/(1+ 1/3)] *12
= [4/(4/3)]*12
= 3*12
= 36
= {4/(1+ (100/3) *(1/100)}*(120)x(0.1)
= [4/(1+ 1/3)] *12
= [4/(4/3)]*12
= 3*12
= 36
