FAQs on Video: Representing Rational Numbers on Number Line: Case 1 Video Lecture - Class 8
| 1. What is a rational number? |  |
Ans. A rational number is a number that can be expressed as a fraction, where both the numerator and denominator are integers. It can be positive, negative, or zero.
| 2. How can rational numbers be represented on a number line? | |
Ans. To represent rational numbers on a number line, we first locate the whole numbers and then divide the interval between two consecutive whole numbers into equal parts. We then plot the rational numbers on these intervals based on their values.
| 3. What is Case 1 in representing rational numbers on a number line? | |
Ans. Case 1 in representing rational numbers on a number line is when the denominator of the fraction is the same. In this case, the interval between two consecutive whole numbers is divided equally based on the denominator, and the numerator determines the position of the fraction on that interval.
| 4. How do you plot a rational number on a number line in Case 1? | |
Ans. To plot a rational number in Case 1, we locate the whole numbers on the number line and divide the interval between them into equal parts based on the denominator. Then, we count the number of parts determined by the numerator and plot the rational number on that position.
| 5. Can all rational numbers be represented on a number line? | |
Ans. Yes, all rational numbers can be represented on a number line. The number line provides a visual representation of the magnitude and order of rational numbers, helping us understand their position in relation to other numbers.
