〖1/1算式〗
    作业：求算式 ((0.1*16.3078*1.0574)/(1+0.1*1.0574))*((100-9.99-0.21)/100)*(1/(1+0.31*0.21))+(2.24/1.31) 的值.
    题型：数学计算
    解:
          ((0.1*16.3078*1.0574)/(1+0.1*1.0574))*((100-9.99-0.21)/100)*(1/(1+0.31*0.21))+(2.24/1.31)
        =(1.724387/(1+0.1*1.0574))*((100-9.99-0.21)/100)*(1/(1+0.31*0.21))+(2.24/1.31)
        =(1.724387/1.10574)*((100-9.99-0.21)/100)*(1/(1+0.31*0.21))+(2.24/1.31)
        =1.559487*((100-9.99-0.21)/100)*(1/(1+0.31*0.21))+(2.24/1.31)
        =1.559487*(89.8/100)*(1/(1+0.31*0.21))+(2.24/1.31)
        =1.559487*0.898*(1/(1+0.31*0.21))+(2.24/1.31)
        =1.559487*0.898*(1/1.0651)+(2.24/1.31)
        =1.559487*0.898*0.938879+(2.24/1.31)
        =1.559487*0.898*0.938879+1.709924
        =1.400419*0.938879+1.709924
        =1.314824+1.709924
        =3.024748
    答案:((0.1*16.3078*1.0574)/(1+0.1*1.0574))*((100-9.99-0.21)/100)*(1/(1+0.31*0.21))+(2.24/1.31)=3.024748
