This math topic focuses on advanced rate and ratio problems. Skills practiced include calculating equivalent ratios and expanding recipes using non-integer multiples exclusively with whole numbers. The problems are couched in practical scenarios involving mixing ingredients for smoothies, sauces, and sundaes, where students must determine the correct amount of one ingredient based on the given amount of another, adhering to a specified ratio. Each question provides a real-world context for understanding and applying the concept of ratios in everyday situations.
