2.0Key Concepts of Chapter 7 Proportional Reasoning 1 Exercise 7.1

• Understanding Direct Proportion: Two quantities x and y are in direct proportion if they increase or decrease together in such a way that $\frac{x}{y}$ remains constant (k).
• The Constant of Variation (k): The fixed ratio between two proportional quantities.
• Unitary Method vs. Proportion Method: While the unitary method finds the value of one unit, the proportion method uses the cross-multiplication of ratios.
• Real-world Examples:
• The more kilometers a car travels, the more petrol it consumes.
• The more hours you work at a fixed rate, the more salary you earn.
