What is direct proportion?
The definition of direct proportion states that "When the relationship between two quantities is such that if we increase one, the other will also increase, and if we decrease one the other quantity will also decrease, then the two quantities are said to be in a direct proportion".
For example, if there are two quantities x and y where x = number of candies and y = total money spent. If we buy more candies, we will have to pay more money, and we buy fewer candies then we will be paying less money. So, here we can say that x and y are directly proportional to each other. It is represented as x ∝ y. Direct proportion is also known as direct variation.
Some real-life examples of direct proportionality are given below:
The number of food items is directly proportional to the total money spent.
Work done is directly proportional to the number of workers.
Speed is in direct proportion to the distance w.r.t a fixed time.
