The diagram shows 2 identical graduated cylinders of 900ml capacity, each containing some water. In order for both cylinders to contain the same amount of water, how much water should be poured from the cylinder on the left into the cylinder on the right? Giúp mik bài này vs nha, cảm ơn. 
Xin chào cả nhà, mình đang làm một dự án và vướng mắc một vấn đề nan giải. Bạn nào có thể đóng góp ý kiến để giúp mình vượt qua không?

Since both cylinders are identical and have the same capacity, pouring half the water from the left cylinder into the right cylinder would make them contain the same amount of water. Therefore, 450 ml of water should be poured from the cylinder on the left into the cylinder on the right.
Có gì không hiểu hỏi mik nha!
