The ratio of milk to water in a container is 5:1 by volume. If the total volume of the mixture is 9 liters, find the volume of water in it.

1/6 = x/9

1 1/2

To find the volume of water in the mixture, we need to use the given ratio of milk to water.

The ratio of milk to water is 5:1, which means that for every 5 parts of milk, there is 1 part of water.

We know that the total volume of the mixture is 9 liters.

Let's set up a proportion to find the volume of water.

5 parts milk: 1 part water = 9 liters total volume : volume of water

Cross-multiplying, we get:

5 * volume of water = 1 * 9

5 * volume of water = 9

Now, we can solve for the volume of water by dividing both sides by 5:

volume of water = 9 / 5

volume of water = 1.8 liters

Therefore, the volume of water in the mixture is 1.8 liters.
