1. What are word problems? Why are they important?
Word problems are the problems that are asked in a detailed manner. They are given in wordings and are expected to solve them mathematically. Students generally will be scared of word problems because sometimes it is difficult to understand. To understand them, students must be good at communication as well as maths. This tests both languages. It is important because the weightage will be given to word problem questions. So if the students did not know how to approach, there are high chances for them to fail.
2. When setting up a proportion, what do we have to consider?
Solving and setting up the proportion is a useful strategy to approach all the reasoning and proportional problems. In such types of problems, it is important to determine the value of the unknown as its first step. The next step will be finding the proportional relationship. Finding their relationship will help you understand the strategy. After this, identify a proportional relationship that can help you identify the unknown value. Our ultimate aim here is to find the unknown value.
3. Why do we use proportion? And the difference between ratio and proportion?
Ratio and proportion are more or less similar to each other. Only certain concepts differ. One such concept is that proportion signifies the equal relationship between two or more ratios but the ratio is used to compare the two things with the same unit.
Proportion is used to determine the relationship between two different ratios. Here we can understand the ratio and the proportion go hand-in-hand. Students must learn this concept because they are carried throughout their academic life. Until grade 12, students will learn this but the standard will be increased every year.
4. What is the property of proportion?
Every concept in mathematics will have its own property and the whole concept will reside by that concept no matter what. Likewise, there is a property for proportion as well. The property states that if two ratios are equal then their reciprocals must also be equal as long as they exist. The product of the extremes is equal to the product of the means. This is a simple property and very interesting to learn. And this property is easy to implement as well. Since the property is easy to understand, the questions based on this topic will also be easily solvable. And the chances of getting direct questions on this topic are high. Though, let us be on the safer side, learn all the important questions and be prepared.
5. How are proportions useful for us in our day-to-day lives?
It is certainly useful for us in our day-to-day lives. A simple example is comparing prices per ounce while grocery shopping, calculating the proper amount of ingredients that are to be added while cooking, calculating how long the car trip will take, sharing the pizza with friends, and a lot more. Everything in our everyday life includes proportion. Proportion is a quantity, used to measure. Thus, wherever measuring is used, proportion must be learned. Get a strong base in this concept which will help you in the long run.
