If 2 cups of rice requires 4.5 cups of water, what is the total number of cups of water needed to prepare 5 cups of the same rice?
Set up a proportion. Cross multiply and solve for x.
2/4.5 = 5/x
2x = 22.5
x = 11.25 cups of water
To find the total number of cups of water needed to prepare 5 cups of rice, we can set up a proportion based on the given information.
Let's call the total number of cups of water needed to prepare 5 cups of rice "x."
We know that 2 cups of rice requires 4.5 cups of water. This means that the ratio of rice to water is 2:4.5.
We can set up a proportion using this ratio:
2 cups of rice / 4.5 cups of water = 5 cups of rice / x cups of water.
Now, we can cross-multiply and solve for "x":
2 * x = 5 * 4.5.
2x = 22.5.
Dividing both sides of the equation by 2:
x = 22.5 / 2.
x = 11.25.
Therefore, the total number of cups of water needed to prepare 5 cups of the same rice is 11.25 cups.
