Answer :
5 oz of a solution contains 4 1/2 oz of water. 20 oz of solution contains 18 oz of water.
We can set up a proportion to solve this problem:
5 oz of solution contains 4 1/2 oz of water, which means that 5 - 4 1/2 = 1/2 oz of the solution is not water.
So the ratio of water to solution is:
4 1/2 oz / 5 oz = x oz / 20 oz
where x is the number of ounces of water in 20 oz of solution.
Cross-multiplying, we get:
5 * x = 4 1/2 * 20
x = (4 1/2 * 20) / 5
x = 18 oz
Therefore, 20 oz of solution contains 18 oz of water.
