六年级数学题!紧急! 单独做完一件工作,甲用a天,乙用b天,丙用c天。甲乙合作(1/(a+b))天完成,乙丙合作(1/(b+c))天完成,甲乙丙合作(1/(a+c))天完成【括号里填式子】下面的是只列式不计算1做完一项工作,甲需要15小时,乙需要10小时,两人同做2小时后,剩下的由甲单独做,还需几小时?【1-(1/15+1/10)*2】÷1/152单独修完一条路,甲用8天,乙的功效是甲的2倍,2人合作,几天修完?1÷(1/8+1/8×2)3一堆货物,甲车单独运玩用4小时,乙车单独运完用6小时,现在两车合运这堆货物的5/6,需要多少小时?5/6÷(1/4+1/6)4甲乙两地相距312千米,轮船从甲到乙需要12小时,货船从乙到甲需要13小时。问题①:两船同时开出,几小时相遇?1÷(1/12+1/13)问题②:如果轮船先行2小说后货船才开出,那么再过几小时相遇?(1-1/12×2)÷(1/12+1/13)5一批化肥,甲车单独运完用15天,乙车则用10天,现在甲车运走总数的1/2后又两车合作运,这样,运完这批化肥,甲共用了几天?1/2÷1/15+1/2÷(1/15+1/10)6修一条水渠,甲队单独修2天可以修完全场的1/8,如果甲乙两队和修全程的4/5,需要七又九分之一天,求乙队的工作效率?1/8÷2=1/164/5÷64/9=9/809/80-1/16=4/80=1/207一直圆珠笔5圆钱,。
