There was 10.9 ℓ of water in a bucket and 1.3 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
= 10.9 - 1.3
= 9.6 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 = 9.6
1 u = 9.6 ÷ 2 = 4.8
Volume of water that Eric poured into each container
= 1 u - 1.3
= 4.8 - 1.3
= 3.5 ℓ
Answer(s): 3.5 ℓ
