Pail Z has five times as much water as Pail Y. If Gabriel adds 0.4 ℓ of water to Pail Z and 2.2 ℓ of water to Pail Y, both pails will have the same volume of water. Find the volume of water in Pail Z at first.

Y |
Z |
| Before |
1 u |
5 u |
| Change |
+ 2.2 |
+ 0.4 |
| After |
1 u + 2.2 |
5 u + 0.4 |
Both pails have the same volume of water in the end.
5 u + 0.4 = 1 u + 2.2
5 u - 1 u = 2.2 - 0.4
4 u = 1.8
1 u = 1.8 ÷ 4 = 0.45
Volume of water in Pail Z at first
= 5 u
= 5 x 0.45
= 2.25 ℓ
Answer(s): 2.25 ℓ
