At first, Pail N and Pail P contained 0.5 ℓ and 1.5 ℓ of water respectively. Some water from Pail P was poured into Pail N with no water spilling over. In the end, there was as much water in Pail N as in Pail P. How much water was poured from Pail P to Pail N?

0.5 ℓ |
1.5 ℓ |
2 ℓ |
Change |
+ 0.5 ℓ |
- 0.5 ℓ |

Difference in the volume of water in Pail N and Pail P
= 1.5 - 0.5
= 1 ℓ
Volume of water poured from Pail P to Pail N
= 1 ÷ 2
= 0.5 ℓ
Answer(s): 0.5 ℓ
