Many real-life situations have direct proportionalities, for example: The work done is directly proportional to the number of workers. The cost of food is directly proportional to weight. The amount of gasoline consumed is proportional to the distance traveled.
Examples of Direct Proportion. 1. Food Preparation at Home. 2. Cost of an Object vs the Number of Objects Purchased. 3. Earning of a Worker per Day. 4. Food Requirement at a Hostel. 5. Petrol Consumption and Distance Travelled. 6. Shadow and Height of Objects. 7. Age and Height of a Person. 8. Time taken and Distance covered by a Vehicle. 9.
16 lis 2023 · Example of Direct Proportion. There are many situations in our daily life where the variation in one quantity brings a variation in the other. Let’s consider and example for better understanding: Suppose we are going to a shop to buy some pencils. And the cost of 2 pencils is Rs.8. then the cost of 4 pencils will also increase and will be Rs.16.
Direct proportion or direct variation is a type of proportion in which the ratio of two quantities stays constant. Suppose a variable y varies directly with x, then it means that if x increases, y increases by the same factor.
The direct proportion formula allows us to express the relationship between two variables, using an equivalence relationship. When y is directly proportional to x, the value of y ÷ x is a constant value. This is known as the constant of proportionality and is represented by the variable k.
Direct proportion is a type of proportionality relationship. For direct proportion, as one value increases, so does the other value and conversely, as one value decreases, so does the other value. The symbol \textbf {∝} ∝ represents a proportional relationship.
Direct proportion is a mathematical comparison between two numbers where the ratio of the two numbers is equal to a constant value. Click to know more about direct proportion along with its formula, graph, and solved examples.
