There was 15.8 ℓ of water in a tank and 2.3 ℓ of water in a pail. Fred 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 Fred pour into each container?

Difference in the volume of water between the tank and the pail
= 15.8 - 2.3
= 13.5 ℓ
Since Fred 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 = 13.5
1 u = 13.5 ÷ 3 = 4.5
Volume of water that Fred poured into each container
= 1 u - 2.3
= 4.5 - 2.3
= 2.2 ℓ
Answer(s): 2.2 ℓ
