A recipe for bread says that the ratio of flour to water should be 3 2 if you use 9 cups how much will need?

Here's how to solve this:

1. Understand the Ratio:

* The ratio 3:2 means for every 3 cups of flour, you need 2 cups of water.

2. Find the Scaling Factor:

* The recipe uses 9 cups of flour, which is 3 times the flour amount in the ratio (9 / 3 = 3).

3. Apply the Scaling Factor to Water:

* Since the flour amount is tripled, you also need to triple the water amount.

* 2 cups of water * 3 = 6 cups of water.

Answer: You will need 6 cups of water.
