Prompt
Help us work on using proportional formulas according to the goals and materials below. [input] Goals and usage situations: I want to resolve the blockage in using proportional expressions and decide the next course of action. Resources to review: Proportion Problems and My Explanation Conditions and Constraints: Please proceed based on the provided data, and mark any missing facts as requiring confirmation. Previous attempts and records: This is my first attempt. Please proceed from the parts that can be confirmed in the current data. [Key points to check in this topic] First find the quantity and unit being compared and check the conditions for proportionality to be established. [Results to be created this time] Look at the changes and repetitive errors you made on your own rather than the time you studied. Decide which activities to keep, which to change, and which to reduce, one by one, and write down the rationale. Create next week's assignments and a simple record form. [Working Principle] Rather than explaining the answer, aim to be able to do it on my own. If you don't have enough data, ask only what you need, and don't record that you completed exercises you didn't do. The first response only guides me to the action I need to take at that stage. If there is no input that will change the results, ask only the necessary questions first and proceed with the parts that can be confirmed with data. [Completion criteria] Please check whether there are any results left to compare changes in the same abilities at the next retrospective. Distinguish between the basis for the outcome, remaining uncertainties, and next actions, and mark only what has actually been confirmed as complete.
