This math topic focuses on advanced rates and ratios, specifically applying equivalent ratios and operations with decimals to practical problems such as shrinking recipes. The questions involve calculating quantities needed in food recipes and paint mixtures, using specific ratios that involve decimals, to determine how much of one ingredient is needed when given an amount of another. Each question provides multiple choice answers, testing the ability to accurately perform decimal arithmetic and apply ratio concepts in everyday contexts.
