This math topic focuses on understanding and calculating percentages, specifically identifying the whole number when a part is given as a multiple of 10% (such as 10%, 20%, etc.). It involves determining what number a given percentage represents. Each question presents a scenario where a smaller number is described as a specific percentage of a larger number, and the goal is to deduce the full value. This skill is essential for solving real-life problems involving percentages, such as calculating discounts, determining proportions, and understanding statistics.
