Pail R has five times as much water as Pail Q. If Carl adds 0.4 ℓ of water to Pail R and 2.6 ℓ of water to Pail Q, both pails will have the same volume of water. Find the volume of water in Pail R at first.

Q |
R |
| Before |
1 u |
5 u |
| Change |
+ 2.6 |
+ 0.4 |
| After |
1 u + 2.6 |
5 u + 0.4 |
Both pails have the same volume of water in the end.
5 u + 0.4 = 1 u + 2.6
5 u - 1 u = 2.6 - 0.4
4 u = 2.2
1 u = 2.2 ÷ 4 = 0.55
Volume of water in Pail R at first
= 5 u
= 5 x 0.55
= 2.75 ℓ
Answer(s): 2.75 ℓ
