This math topic focuses on practicing calculations with equivalent ratios and their application to real-life scenarios, such as mixing ingredients in recipes. Students are tasked with adjusting recipe amounts using non-integer multiples and decimals to solve problems that involve scaling ratios to find quantities of various components, specifically in a context of mixing colors or ingredients in food items. Questions are provided for students to determine the exact amount needed of one ingredient based on a given amount of another, with immediate feedback options (multiple choice answers). These problems build skills in proportional reasoning and solution of ratio problems involving decimals.
