Solve the following using this ratio
263 grams dental stone powder
80 milliliters of water

If you use 79 grams of stone, how many milliliters of water are needed?
milliliters of water are needed
(Round to the nearest whole number as needed.)

Step 1 ：We are given that 263 grams of dental stone powder requires 80 milliliters of water. We need to find out how many milliliters of water are needed for 79 grams of stone.

Step 2 ：We can set up a proportion to solve this problem. The proportion is \( \frac{263}{80} = \frac{79}{x} \).

Step 3 ：Solving for x will give us the amount of water needed for 79 grams of stone.

Step 4 ：The calculated amount of water needed for 79 grams of stone is approximately 24.03 milliliters.

Step 5 ：However, the question asks for the answer to be rounded to the nearest whole number.

Step 6 ：So, the rounded amount of water needed for 79 grams of stone is 24 milliliters.

Step 7 ：Final Answer: The amount of water needed for 79 grams of stone is approximately \(\boxed{24}\) milliliters.
