243. A straight pipe 1 yard in length was marked off in fourths and also in thirds. If the pipe was then cut into separate pieces at each of these markings, which of the following gives all the different lengths of the pieces, in fractions of a yard?

上面红色部分啥意思啊？谢咯

划分成1/4的小段和1/3的小段

即：把1yard的pipe分别划成1/4,2/4,3/4和1/3,2/3处标记
