This math topic focuses on understanding and calculating totals from given item ratios. It includes problems where learners must determine the total number of items (such as kids or balls) based on given ratios between two categories (like boys to girls or tennis balls to soccer balls). The topic is a beginner-level introduction to rates and ratios, helping learners develop skills in interpreting and solving ratio problems to find total quantities in various contexts.
