RD Sharma Class 7 Solutions Chapter 9 - Ration And Proportion (Ex 9.1) Exercise 9.1 - Free PDF
FAQs on RD Sharma Class 7 Solutions Chapter 9 - Ration And Proportion (Ex 9.1) Exercise 9.1
1. Where can I find clear, step-by-step solutions for RD Sharma Class 7 Maths, Exercise 9.1?
You can find detailed and easy-to-understand solutions for every question from RD Sharma Class 7 Maths Chapter 9, Exercise 9.1, right here. Our solutions are prepared by subject experts to help you understand the correct method for solving each problem related to ratios and their comparison.
2. How do the RD Sharma solutions explain the method for comparing two different ratios in Exercise 9.1?
The solutions demonstrate the standard method for comparing ratios. The first step is to convert the ratios into fractions. Then, you find the LCM (Least Common Multiple) of the denominators to make them equal. Once the denominators are the same, you can easily compare the numerators to determine which ratio is larger or smaller.
3. Are the problem-solving methods in these solutions suitable for my school exams?
Yes, absolutely. The methods used in our RD Sharma solutions are based on the fundamental principles of the Class 7 Maths syllabus. They provide a logical, step-by-step approach that is perfect for building conceptual clarity and for writing answers that will score full marks in your school exams.
4. What types of questions from Exercise 9.1 are covered in these solutions?
These solutions cover all problems in Exercise 9.1, which primarily focuses on the fundamentals of ratios. You will find solved examples for:
- Expressing quantities as a ratio in its simplest form.
- Comparing two or more ratios to find the greater one.
- Arranging a set of ratios in ascending or descending order.
- Solving basic word problems that require setting up a ratio.
5. Why is it so important to have the same units when finding a ratio, as shown in the Chapter 9 solutions?
This is a critical rule because a ratio is a comparison of two quantities of the same kind. If you compare metres to centimetres directly, the comparison is meaningless. The solutions guide you to first convert both quantities to the same unit (e.g., both in cm or both in m). This ensures that you are comparing 'like with like' and your final ratio is accurate.
6. I often confuse a ratio with a fraction. How do the solutions for this chapter help clear this up?
That's a very common doubt. While a ratio like 3:4 can be written as the fraction 3/4, their meanings differ. A fraction represents a part of a single whole. A ratio compares two separate quantities. The problems in Exercise 9.1, like comparing the number of boys to girls, help you practice setting up ratios as a comparison, which makes the difference clearer.
7. Is it enough to just read the RD Sharma solutions to master Ratio and Proportion?
Reading the solutions is a great way to understand the correct method, but true mastery comes from practice. The best approach is to try solving the exercise problems on your own first. If you get stuck, use the solutions as a guide to understand the logic. Focus on why a certain step was taken. This will help you solve any similar problem, not just the ones in the book.
