FAQs on Examples: Inverse Proportions Video Lecture - Mathematics (Maths) Class 8
| 1. What is an inverse proportion? |  |
Ans. Inverse proportion is a mathematical relationship between two variables where an increase in one variable results in a decrease in the other variable, and vice versa. Inverse proportions can be represented by the equation y = k/x, where y and x are the variables and k is a constant.
| 2. How can inverse proportions be identified in a graph? | |
Ans. In a graph, inverse proportions can be identified by observing a hyperbolic curve. As one variable increases, the other variable decreases, forming a curve that approaches but never reaches the axes. The slope of the curve also changes as the values of the variables change.
| 3. Can you provide an example of inverse proportion in real life? | |
Ans. Yes, a common example of inverse proportion in real life is the relationship between speed and time during a journey. If the speed of a vehicle remains constant, the time taken to complete the journey will be inversely proportional to the distance traveled. As the distance increases, the time taken to cover that distance decreases.
| 4. How can inverse proportions be solved mathematically? | |
Ans. To solve inverse proportions, we can use the formula y = k/x. We can set up a proportion equation using this formula and solve for the unknown variable. Cross-multiplication can be used to simplify the equation and find the value of the unknown variable.
| 5. Are there any limitations or exceptions to inverse proportions? | |
Ans. Yes, there can be limitations or exceptions to inverse proportions. Inverse proportions assume that other factors remain constant and that the relationship between the variables is linear. Non-linear relationships may not follow inverse proportionality. Additionally, some real-life scenarios may have more complex relationships where inverse proportionality is not applicable.
