This math chapter workbook on "Percents" lets students practice and reinforces how percentages, fractions, and decimals are interrelated. Students practice converting between these forms (e.g., changing a fraction like 3/4 into a percent and a decimal). Students learn how to calculate percentages of numbers, such as finding 25% of 200 or determining what percent one number is of another. Real-world applications, such as calculating discounts, tax, and interest, are also included to make the concept relevant and engaging.

Students can encounter engaging problems designed to build their understanding of this concept. One common type of problem might require students to calculate the percentage of a number, such as finding 25% of 80. To solve this, students can either convert the percentage to a fraction (25/100) and multiply it by 80, or simply multiply 80 by 0.25 (the decimal form of 25%). Another problem might involve determining what percentage one number is of another, such as finding what percent 30 is of 120.
