There was 6.9 ℓ of water in a bucket and 1.7 ℓ of water in a pail. Brandon 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 Brandon pour into each container?

Difference in the volume of water between the bucket and the pail
= 6.9 - 1.7
= 5.2 ℓ
Since Brandon 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 = 5.2
1 u = 5.2 ÷ 2 = 2.6
Volume of water that Brandon poured into each container
= 1 u - 1.7
= 2.6 - 1.7
= 0.9 ℓ
Answer(s): 0.9 ℓ
