There was 7.9 ℓ of water in a pail and 2.3 ℓ of water in a basin. Cody then poured in an equal volume of water into each container. Now, the volume of water in the pail is 3 times in the basin. How much water did Cody pour into each container?

Difference in the volume of water between the pail and the basin
= 7.9 - 2.3
= 5.6 ℓ
Since Cody 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 = 5.6
1 u = 5.6 ÷ 2 = 2.8
Volume of water that Cody poured into each container
= 1 u - 2.3
= 2.8 - 2.3
= 0.5 ℓ
Answer(s): 0.5 ℓ
