FAQs on Direct and Inverse Proportions Video Lecture - Mathematical Olympiad Class 8
| 1. How can direct and inverse proportions be distinguished? |  |
Ans. In direct proportion, as one quantity increases, the other also increases, while in inverse proportion, as one quantity increases, the other decreases.
| 2. Can you provide an example of direct proportion? | |
Ans. Yes, an example of direct proportion is the relationship between the number of hours worked and the amount of money earned - the more hours worked, the more money earned.
| 3. What is the equation to represent inverse proportion? | |
Ans. The equation to represent inverse proportion is y = k/x, where y is one quantity, x is the other quantity, and k is a constant.
| 4. How can inverse proportionality be visually represented on a graph? | |
Ans. Inverse proportionality can be visually represented on a graph by a hyperbola, where the curve approaches but never reaches the x and y axes.
| 5. Can direct and inverse proportions exist simultaneously in a given situation? | |
Ans. Yes, direct and inverse proportions can exist simultaneously in a given situation. For example, the time taken to travel a certain distance is inversely proportional to the speed at which one travels, but directly proportional to the distance traveled.
