简便运算:2.5*(88+7/15)*4+8*(1/3)*(5/4)-125%*(78+2/3)*8-8/9*1.5
2.5*(88+7/15)*4+8*(1/3)*(5/4)-125%*(78+2/3)*8-8/9*1.5
=2.5*4*(88+7/15)+8*(5/4)*(1/3)-125%*8*(78+2/3)-8/9*1.5
=10*(88+7/15)+10*(1/3)-10*(78+2/3)-8/9*1.5
=10*(88+7/15+1/3-78-2/3)-8/9*1.5
=10*(10+2/15)-8/9*1.5
=100+20/15-8/9*3/2
=100+4/3-4/3
=100
