This math topic focuses on calculating the total quantity from a given ratio of items or groups. Problems involve finding total numbers of pets, kids, or balls based on specific ratios, such as cats to dogs, boys to girls, or tennis balls to soccer balls. Each scenario provides one part of the ratio and asks the learner to use the given ratio to determine the total count of all items involved. The exercises are designed to help enhance understanding of ratios and proportional reasoning, which are integral components of the broader topic of rates and ratios.
