This math topic focuses on understanding and applying the concept of equivalent ratios. The problems specifically involve calculating proportional quantities in practical situations such as adjusting recipe ingredients (e.g., paint colors or food sauces) based on given ratios. Students are given initial ratios between two ingredients and must determine the amount of one ingredient needed when provided with a different amount of the other ingredient. This helps strengthen their ability to work with ratios, proportions, and practical application of integer multiples with whole numbers.
