Common mistakes
What learners typically get wrong, and how to fix it.
Students treat core ratios as a rule to memorise rather than a relationship to understand.
Correction: Anchor the rule in a visual model first, then abstract it — the model is the explanation.
Learners apply the correct method to core ratios but ignore the context or units.
Correction: Require an answer sentence with units on every applied question.
