〖1/1算式〗
    作业：求算式 ((0.1*16.3078*1.0574)/(1+0.1*1.0574))*((100-0.0999-0.0021)/100)*(1/(1+0.31*0.0021))+(2.24/1.31) 的值.
    题型：数学计算
    解:
          ((0.1*16.3078*1.0574)/(1+0.1*1.0574))*((100-0.0999-0.0021)/100)*(1/(1+0.31*0.0021))+(2.24/1.31)
        =(1.724387/(1+0.1*1.0574))*((100-0.0999-0.0021)/100)*(1/(1+0.31*0.0021))+(2.24/1.31)
        =(1.724387/1.10574)*((100-0.0999-0.0021)/100)*(1/(1+0.31*0.0021))+(2.24/1.31)
        =1.559487*((100-0.0999-0.0021)/100)*(1/(1+0.31*0.0021))+(2.24/1.31)
        =1.559487*(99.898/100)*(1/(1+0.31*0.0021))+(2.24/1.31)
        =1.559487*0.99898*(1/(1+0.31*0.0021))+(2.24/1.31)
        =1.559487*0.99898*(1/1.000651)+(2.24/1.31)
        =1.559487*0.99898*0.999349+(2.24/1.31)
        =1.559487*0.99898*0.999349+1.709924
        =1.557896*0.999349+1.709924
        =1.556882+1.709924
        =3.266806
    答案:((0.1*16.3078*1.0574)/(1+0.1*1.0574))*((100-0.0999-0.0021)/100)*(1/(1+0.31*0.0021))+(2.24/1.31)=3.266806
