Container X has five times as much water as Container W. If Perry adds 0.7 ℓ of water to Container X and 1.7 ℓ of water to Container W, both containers will have the same volume of water. Find the volume of water in Container X at first.

| Before |
1 u |
5 u |
| Change |
+ 1.7 |
+ 0.7 |
| After |
1 u + 1.7 |
5 u + 0.7 |
Both containers have the same volume of water in the end.
5 u + 0.7 = 1 u + 1.7
5 u - 1 u = 1.7 - 0.7
4 u = 1
1 u = 1 ÷ 4 = 0.25
Volume of water in Container X at first
= 5 u
= 5 x 0.25
= 1.25 ℓ
Answer(s): 1.25 ℓ
