Answer 3

Problem Analysis

In this problem, we are given two containers of milk, each containing 20 liters. The children in the kindergarten drank 12 liters of milk during breakfast. We need to determine how much milk is left.

Solution 1: Subtraction

One way to solve this problem is by subtracting the amount of milk consumed from the total amount of milk available.

To find the amount of milk left, we subtract 12 liters (amount consumed) from 40 liters (total amount of milk).

Solution: The amount of milk left is 28 liters.

Solution 2: Addition and Subtraction

Another way to solve this problem is by adding the amount of milk consumed to the amount of milk left in the second container.

Since each container contains 20 liters of milk, the total amount of milk available is 40 liters.

We subtract the amount consumed (12 liters) from the total amount of milk (40 liters) to find the amount of milk left in the second container.

Solution: The amount of milk left in the second container is 28 liters.

Solution 3: Multiplication

We can also solve this problem using multiplication.

Since each container contains 20 liters of milk, the total amount of milk available is 40 liters.

We can find the amount of milk left by multiplying the number of containers (2) by the amount of milk in each container (20 liters) and then subtracting the amount consumed (12 liters).

Solution: The amount of milk left is 28 liters.

Conclusion

In all three solutions, we find that the amount of milk left is 28 liters.
