project takes 1 hour and 36 minutes to complete by A alone, and it takes 1 hour for A and B to complete it together. Now A alone completes (1/12), A and B work together, but because A takes a break on the way, the whole work takes 1 hour and 38 minutes to complete, so the part that B alone takes account for a fraction of the whole project Several?
一项工程，甲一人需1小时36分完成，甲、乙二人合作要1小时完成．现在由甲一人完成(1/12)以后，甲、乙二人一起干，但因途中甲休息，全部工作用了1小时38分完成，那么由乙单独做那部分占全部工程的几分之几？
