This math topic focuses on solving problems related to equivalent ratios and expanding recipes using integer multiples with decimals. The problems require calculating amounts needed when given a specific ratio and an initial quantity. For example, if a recipe requires a certain amount of one ingredient for every certain amount of another, students must determine how much of the first ingredient is needed if the quantity of the second ingredient is increased, focusing on precision with decimal measurements. These exercises are aimed at strengthening understanding and application of ratio concepts in practical scenarios involving measurements.
