Explanation
This question tests SSAT Middle Level skills: interpreting and simplifying ratios. A ratio represents a relationship between two quantities, showing how many times one value contains or is contained within the other. In this scenario, the specific quantities given are 15 cups of sugar and 45 cups of flour and students need to simplify the ratio by finding the greatest common divisor. Choice A is correct because it accurately simplifies the ratio 15:45 to 1:3, demonstrating an understanding of the relationship. Choice B is incorrect because it reflects a common error of reversing the order, which happens when students switch the items. To help students, encourage them to always check their work by verifying that both parts of the ratio can no longer be divided by the same number. Emphasize the importance of understanding the context of the ratio to avoid reversing quantities.
