This math topic focuses on practicing equivalent ratios and their application in real-world scenarios, specifically in recipes and mixing ingredients. Students learn to calculate the necessary quantities when given ratios and base measures, adjusting proportions to different amounts. The problems use scenarios like adjusting the amount of strawberry in a sundae or peach in a smoothie, relative to another ingredient, based on given ratios. Questions are presented in a multiple-choice format, enhancing skills in proportional reasoning and practical application of ratios.
