This detailed lesson explores increasing or decreasing of a number in a given ratio through thorough explanations, carefully worked examples, structured practice activities, and meaningful practical contexts. In this video, we master the skill of increasing or decreasing a number using a given ratio. You’ll learn the simple method of multiplying your original amount by a fraction to find its new value, whether you're scaling a recipe up or calculating a price reduction. With clear, step-by-step examples, this video shows you exactly how to set up your calculations so you can grow or shrink any quantity with total accuracy.. The lesson starts by examining the essential ideas, terminology, and principles related to increasing or decreasing of a number in a given ratio, allowing learners to establish a solid understanding before progressing to more advanced material. Students will investigate the significance of the topic, examine its practical uses in different situations, and identify frequent errors together with strategies for avoiding them. A variety of carefully selected examples are analysed in a logical sequence, enabling learners to understand the underlying reasoning and gradually build confidence in using the skill on their own. Relevant links to prior learning are highlighted throughout, while connections to later concepts help learners see how the knowledge can be extended and applied in future studies. Upon completing the lesson, learners should be able to describe increasing or decreasing of a number in a given ratio clearly, apply appropriate techniques with accuracy, tackle related tasks successfully, and appreciate how the topic contributes to stronger reasoning, problem-solving, and analytical skills.
