A tractor plows a piece of land. It plows (1/2) of the land on the first day and the rest (1/3) on the second day. What fraction of the land is plowed on the second day? (First find out what fraction of the land the rest on the first day occupies, and then find out what (1/3) of it is.)
拖拉机耕一块地，第一天耕了这块地的(1/2)，第二天耕了余下的(1/3)，第二天耕了这块地的几分之几？(先求第一天余下的占这块地的几分之几，再求出它的(1/3)是多少．)
