There is more water (1/5) in bucket A than in bucket B, and less water in bucket C than in bucket A (1/5). May I ask: Which of the two barrels B and C has more water? If three buckets of water are poured into a large tank, what percentage of the water in bucket A accounts for it?
甲桶中的水比乙桶中的多(1/5)，丙桶中的水比甲桶中的少(1/5)．请问：乙、丙两桶哪桶水多？如果把三桶水倒人一个大缸里，甲桶中的水占其中的几分之几？
