Recognizing Proportional Relationships Worksheets
Tips For Recognizing Proportional Relationships - Proportion plays a very important role in your life. If you look around yourself, you will find everything coming in proportion to you. Before we begin with the tips for identifying proportional relationships between quantities, take a look at the examples around you. The word proportion is used as a synonym for ratio. In fact, both terms are interchangeable. Taking an example from our everyday life; the relationship between the liters of petrol we put in our car and the money we pay for the fuel has a proportional relationship. The more petrol we put in the tank, the more we have to pay for it. Similarly, the less we put into the tank, the fewer bucks we have to have to pay. It is a directly proportional relationship between fuel and money. In a given problem, you can identify the proportional relationship by following the below-mentioned steps: - Look for the variable in the problem. - Take a look at their ratios and see either they are equivalent or not. If they are equivalent, they are proportional variables, and if the ratios aren't equivalent the variables aren't proportional. - You can also identify a constant value in the problem to identify the proportional relationship because one variable is always a constant value times the other, known as the ‘constant of proportionality'.
