There was 8.4 ℓ of water in a bucket and 2.2 ℓ of water in a pail. Billy 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 Billy pour into each container?

Difference in the volume of water between the bucket and the pail
= 8.4 - 2.2
= 6.2 ℓ
Since Billy 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 = 6.2
1 u = 6.2 ÷ 2 = 3.1
Volume of water that Billy poured into each container
= 1 u - 2.2
= 3.1 - 2.2
= 0.9 ℓ
Answer(s): 0.9 ℓ
