这个你可以去书店翻翻书,在这问估计问不到什么的
5/6+1/3=4/7+2/5+3/7+3/5=2/15+3/8=4/9-2/7=(4/8+1/2)-(6/8-1/3)=3/5-6/10=7/12+21/36=9/18-1/9=5/15-1/5=1
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

怎么没有问题?再问:问题就是:100道分数小数混合运算,要过程和答案再答:hoho
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)
1/7+3/8+5/7=1/7+5/7+3/8=6/7+3/8=48/56+21/56=69/56先分母相同进行运算,再约分1-5/9-4/9=1-(5/9+4/9)=1-1=0连减几个数,等于减去这
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)
1/2÷4/5÷(2/9×3/8)=1/2*5/4除以1/12=5/2*12=30(5/6-3/4)÷5/12÷9/5=1/12*12/5*5/9=1/93/7÷[5/7-(3/7+1/5)=3/7除
