This math topic focuses on calculating unit rates, both for costs (in terms of $/kg) and wages (in terms of $/hr). Learners are provided with problems where they need to find the unit price from total cost and total weight, or compute the hourly wage from total earnings and hours worked. The problems are structured with multiple-choice answers, encouraging the application of division to find rates in practical contexts. These exercises are part of an introductory unit on rates and ratios.
