There was 7.9 ℓ of water in a tank and 1.3 ℓ of water in a pail. Wesley then poured in an equal volume of water into each container. Now, the volume of water in the tank is 4 times in the pail. How much water did Wesley pour into each container?

Difference in the volume of water between the tank and the pail
= 7.9 - 1.3
= 6.6 ℓ
Since Wesley 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.
3 u = 6.6
1 u = 6.6 ÷ 3 = 2.2
Volume of water that Wesley poured into each container
= 1 u - 1.3
= 2.2 - 1.3
= 0.9 ℓ
Answer(s): 0.9 ℓ
