Tank W has five times as much water as Tank V. If Michael adds 1.1 ℓ of water to Tank W and 2.9 ℓ of water to Tank V, both tanks will have the same volume of water. Find the volume of water in Tank W at first.

V |
W |
| Before |
1 u |
5 u |
| Change |
+ 2.9 |
+ 1.1 |
| After |
1 u + 2.9 |
5 u + 1.1 |
Both tanks have the same volume of water in the end.
5 u + 1.1 = 1 u + 2.9
5 u - 1 u = 2.9 - 1.1
4 u = 1.8
1 u = 1.8 ÷ 4 = 0.45
Volume of water in Tank W at first
= 5 u
= 5 x 0.45
= 2.25 ℓ
Answer(s): 2.25 ℓ
