There was 15.9 ℓ of water in a bucket and 1.1 ℓ of water in a pail. Pierre then poured in an equal volume of water into each container. Now, the volume of water in the bucket is 5 times in the pail. How much water did Pierre pour into each container?

Difference in the volume of water between the bucket and the pail
= 15.9 - 1.1
= 14.8 ℓ
Since Pierre 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.
4 u = 14.8
1 u = 14.8 ÷ 4 = 3.7
Volume of water that Pierre poured into each container
= 1 u - 1.1
= 3.7 - 1.1
= 2.6 ℓ
Answer(s): 2.6 ℓ
