7. What are the properties of rational numbers?

Properties of rational numbers includes commutative, associative, additive, and closure properties. Students must understand the different properties of rational numbers to get high marks in Class 8 Maths.

8. What do you mean by associative property of rational numbers according to Chapter 1 of Class 8 Maths?

**Ans: **The associative property of rational numbers means that if you add three or more rational numbers in any sequence the result will be the same. Rational numbers follow the associative property of addition and multiplication. According to the associative property of multiplication, if you multiply two or more rational numbers in any sequence the result will be the same. Thus, according to this property, students can add or multiply two or more rational numbers in any order to get the right result.

9. What is the closure property of rational numbers according to Chapter 1 of Class 8 Maths?

**Ans: **The closure property of rational numbers states that if you add, subtract, or multiply two rational numbers you will get a rational number. Rational numbers are not closed for division because if you divide a rational number by zero, you will not get a rational number. Thus, the closure property of rational numbers does not fit for division.

10. What are terminating and non-terminating decimals in rational numbers?

Terminating decimals are rational numbers with decimal representations that end, such as 0.25 or 0.5. Non-terminating decimals are rational numbers with decimal representations that continue indefinitely, either repeating or not repeating in a pattern.

11. Are there any specific techniques for solving problems involving rational numbers?

One useful technique is to convert mixed numbers to improper fractions before performing operations. Additionally, when adding or subtracting fractions, it's helpful to find a common denominator to make calculations easier.

12. What are some real-life examples of rational numbers?

Examples of rational numbers in real life include measurements such as distances, weights, and temperatures, as well as fractions representing parts of a whole, such as $\dfrac{3}{4}$ of a pizza or $\dfrac{2}{5}$ of a liter.

13. How can I practice Class 8 Maths Rational Numbers Important Questions?

You can practice extra questions on rational numbers by downloading additional worksheets or PDFs available online or using textbooks with supplementary exercises. These resources typically provide a variety of problems to reinforce your understanding of the topic.

14. What is the difference between rational and irrational numbers?

Rational numbers can be expressed as fractions, while irrational numbers cannot be expressed as fractions and have non-terminating and non-repeating decimal expansions. For example, $\sqrt{2}$ and $\pi$ are irrational numbers.

15. How can we perform operations on rational numbers?

Operations such as addition, subtraction, multiplication, and division can be performed on rational numbers using rules similar to those for integers. For division, we need to ensure that the divisor is not zero.
