Accepted Answer

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.

Question 4

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

Accepted Answer

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.

Question 5

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

Accepted Answer
