Ratios - Calculate Value from Total and Item Ratio

Level 1

This math topic focuses on calculating specific values from a total given a ratio between items. It presents problems where students learn to find the number of girls, boys, dogs, or specific types of balls by using the total number and a ratio (e.g., boys to girls or tennis balls to soccer balls). Each problem provides a total quantity and a ratio, and students must use this information to find the quantity of one of the items specified in the ratio. This skill is useful in understanding proportions and applying them to practical scenarios.
