Answer 2

Problem Analysis

We have a container with 39 liters of milk. After filling several two-liter jars, there are 7 liters of milk left in the container. We need to determine how many jars were filled.

Solution

To find the number of jars filled, we need to calculate the difference between the initial amount of milk in the container and the remaining amount of milk.

The initial amount of milk in the container is 39 liters, and the remaining amount of milk is 7 liters. Therefore, the amount of milk used to fill the jars is 39 - 7 = 32 liters.

Since each jar can hold 2 liters of milk, we can divide the amount of milk used to fill the jars by the capacity of each jar to find the number of jars filled.

The number of jars filled is 32 / 2 = 16 jars.

Therefore, 16 jars were filled with milk from the container.

Conclusion

After filling several two-liter jars, 16 jars were filled with milk from the container, leaving 7 liters of milk remaining.
