Direct proportion occurs when two quantities increase or decrease together, such that their ratio remains constant (e.g., more land yields more crops).
What is inverse proportion?
Inverse proportion occurs when one quantity increases as the other decreases, keeping their product constant (e.g., more workers reduce work time).
How is proportion used in Assam’s agriculture?
Proportion is used to calculate crop yields based on land size or estimate labor costs based on work time.
What types of questions are in Exercises 13.1 and 13.2?
Exercise 13.1 focuses on identifying direct and inverse proportions, while 13.2 includes word problems and applications of proportion.
