This math topic focuses on understanding how to express percentages as equivalent fractions and solve for missing values within percent problems. The exercises require students to identify the percentage represented by a given fraction of a whole, or conversely, to determine the whole or the part when the percentage and one of the components are known. Each question includes an array representing parts and wholes with their corresponding percentages, and students must select the correct answer from multiple choices. This topic serves as an introductory exploration of percentages, laying the groundwork for more complex problems in this area.
