Question: 1 / 400

You fill two 18 inch containers with stream water. If one is 8/18 inches full and the other is 5/18 inches full, how much less water is in the second container?

1/4 inches

1/5 inches

1/6 inches

To find out how much less water is in the second container compared to the first, you start by determining the amounts of water in both containers.

The first container is filled with 8/18 inches of water, while the second container has 5/18 inches of water. To find the difference between these two amounts, you subtract the amount of water in the second container from the amount in the first container:

8/18 - 5/18 = (8 - 5)/18 = 3/18 inches.

Now, to simplify 3/18, you can divide both the numerator and the denominator by their greatest common divisor, which is 3:

3/18 = 1/6 inches.

This indicates that the first container has 1/6 inches more water than the second container. Therefore, when asked how much less water is in the second container, the answer is indeed 1/6 inches, aligning with the correct choice. This calculation clarifies the relationship between the two amounts of water in the context of the question.
