你可以去看文库嘛:看看这是不是你需要的
1.3/7×49/9-4/32.8/9×15/36+1/273.12×5/6–2/9×34.8×5/4+1/45.6÷3/8–3/8÷66.4/7×5/9+3/7×5/97.5/2-(3/2+4/5)
6x+3/10+10×60.18-18.1=6446x+3/10+10×60.28-28.1=6356x+3/10+10×60.38-38.1=6266x+3/10+10×60.48-48.1=617
方法一:80÷(80÷15+80÷40)=80÷(16/3+2)=80÷22/3=120/11小时方法二:1÷(1÷15+1÷40)=1÷(1/15+1/40)=1÷11/120=120/11小时
60+7/35+35×60.09-9.35=215460+7/35+35×60.29-29.35=214160+7/35+35×60.49-49.35=212860+7/35+35×60.69-69.
