There was 9.2 ℓ of water in a bucket and 2.8 ℓ of water in a pail. Eric then poured in an equal volume of water into each container. Now, the volume of water in the bucket is 3 times in the pail. How much water did Eric pour into each container?

Difference in the volume of water between the bucket and the pail
= 9.2 - 2.8
= 6.4 ℓ
Since Eric poured in an equal volume of water into each container, the difference in the volume of water at first and in the end remains the same.
2 u = 6.4
1 u = 6.4 ÷ 2 = 3.2
Volume of water that Eric poured into each container
= 1 u - 2.8
= 3.2 - 2.8
= 0.4 ℓ
Answer(s): 0.4 ℓ
