Introduction (10 minutes): 1. Begin the lesson by asking the students if they know what “net profit” means. Discuss briefly and explain that net profit is the amount of money a company or individual earns after deducting all expenses. 2. Write the term “net profit” on the board and ask students if they have any idea how fractions and mixed numbers can be related to it.

Convert any mixed numbers to improper fractions if necessary. d. Perform the operation and simplify the answer if possible. e. Check the answer for reasonableness and accuracy. 5. Model the process of solving a problem on the board, using one of the examples from the worksheet. Explain each step and encourage students to ask questions if they need clarification. 6. Allow students to work individually or in pairs to solve the remaining problems on the worksheet. Circulate the classroom to provide support and guidance as needed. 7. After sufficient time, review the answers as a class, discussing the strategies used and any common errors made. Emphasize the importance of checking the reasonableness of the answers.

Conclusion (10 minutes): 8. Summarize the lesson by highlighting the key points discussed, such as the meaning of net profit and how fractions and mixed numbers can be used to solve problems related to it. 9. Engage the students in a brief discussion about the importance of understanding fractions and mixed numbers in real-life situations, such as managing personal finances or running a business. 10. Assign additional practice problems or homework to reinforce the concepts learned in the lesson.
