Solution
Step 1 ：The question is asking for the amount of ice cubes Stan should use if he's going to use 3 pieces of fruit. Given the ratio of ice cubes to fruit is 4:1, we can set up a proportion to solve for the unknown.
Step 2 ：Let's denote the ratio of ice cubes to fruit as \(\frac{4}{1}\).
Step 3 ：Let's denote the amount of fruit Stan is going to use as 3.
Step 4 ：By cross multiplying, we can find the amount of ice cubes Stan should use: \(4 \times 3 = 12\).
Step 5 ：Final Answer: Stan should use \(\boxed{12}\) ice cubes if he's going to use 3 pieces of fruit.
