This math topic focuses on calculating total numbers using given ratios. The problems involve ratio expressions with missing elements, and the task is to determine the total count of a group (e.g., kids, pets, or balls) using the ratios of subgroups to the total group. Learners practice interpreting part-to-whole relationships and solving for unknown wholes. The topic blends practical ratio problems with different subjects, including boys to girls, cats to dogs, and tennis to soccer balls, enhancing varied contextual understanding of ratios.
