FAQs on 06 - Finding Rational Numbers - Class 10 - Maths Video Lecture

1. What are rational numbers?
Ans. Rational numbers are numbers that can be expressed in the form of p/q, where p and q are integers and q is not equal to zero. These numbers can be positive, negative, or zero and can be expressed as fractions or terminating or repeating decimals.
2. How do you find rational numbers?
Ans. To find rational numbers, we need to check if a given number can be expressed as a fraction. If a number can be expressed as p/q, where p and q are integers and q is not equal to zero, then the number is a rational number.
3. Can irrational numbers be rational?
Ans. No, irrational numbers cannot be rational. Rational numbers can be expressed as fractions or terminating or repeating decimals, whereas irrational numbers cannot be expressed as fractions and have non-repeating, non-terminating decimal expansions.
4. How can rational numbers be represented on a number line?
Ans. Rational numbers can be represented on a number line by marking the position of the number between the two integers. For example, if we have a rational number 3/4, we can mark it between the integers 0 and 1 on the number line.
5. What is the difference between rational and irrational numbers?
Ans. The main difference between rational and irrational numbers is that rational numbers can be expressed as fractions or terminating or repeating decimals, while irrational numbers cannot be expressed as fractions and have non-repeating, non-terminating decimal expansions. Additionally, rational numbers can be represented on a number line, whereas irrational numbers cannot be accurately represented on a number line.
