FAQs on Decimals on Number Line Video Lecture - Mathematics (Ganita Prakash) Class 7 - New NCERT

1. What is a decimal and how is it represented on a number line?

Ans. A decimal is a fraction whose denominator is a power of ten, and it is represented using a decimal point. On a number line, decimals are positioned between whole numbers. For example, 0.5 is located halfway between 0 and 1.

2. How do you locate a decimal on a number line?

Ans. To locate a decimal on a number line, first identify the whole numbers it is between. Divide the space between these whole numbers into equal parts based on the decimal's place value. For instance, to find 0.3, divide the segment between 0 and 1 into ten equal parts and count three parts from 0.

3. What are the steps to compare two decimals on a number line?

Ans. To compare two decimals, first locate both decimals on the number line. Observe their positions relative to each other. The decimal further to the right is greater. For example, if 0.4 is to the left of 0.7, then 0.4 is less than 0.7.

4. Why is it important to understand decimals on a number line in mathematics?

Ans. Understanding decimals on a number line helps students visualize the size of decimals and their relationships with whole numbers and other decimals. This visualization aids in addition, subtraction, and comparing decimal values, which are crucial skills in mathematics.

5. Can you give an example of adding decimals using a number line?

Ans. Yes! To add 0.4 and 0.3 using a number line, start at 0.4 and move three spaces to the right (to represent 0.3). You will land on 0.7, which is the sum of 0.4 and 0.3.
