Two people, A and B, go from A to B at the same time. When A travels (3/4) of the whole journey, B travels (2/3) of the whole journey. According to this calculation, when A reaches the end point, B travels the whole journey ((())/(())).
甲乙二人同时从A地到B地，当甲行全程的(3/4)时，乙行全程的(2/3)．照这样计算，甲到达终点时，乙行全程的((())/(()))．
