Question 8.

Show the following numbers on the number line.

**(a)** 0.2

**(b)** 1.9

**(c)** 1.1

**(d)** 2.5

Solution:

**(a)** Since 0.2 > 0 but <1. There are 2 tenth in it. Divide the unit length between 0 and 1 into 10 equal parts and take 2 parts as shown below. Thus, A represents 0.2.

**(b)** Since 1 < 1.9 < 2. Divide the unit length between 1 and 2 into 10 equal parts and take 9 parts as shown below. Thus, A represents 1.9.

**(c)** Since 1 < 1.1 < 2. Divide the unit length between 1 and 2 into 10 equal parts and take 1 part as shown below. Thus, A represents 1.1.

**(d)** Since 2 < 2.5 < 3. Divide the unit length between 2 and 3 into 10 equal parts and take 5 parts as shown below. Thus, A represents 2.5.

Question 9.

Write the decimal number represented by the points A, B, C, D on the given number line

Solution:

Since A lies between 0 and 1 and the unit length between 0 and 1 stands divided in 10 equal parts. Also A is at the 8th point.

Thus, A represents 0.8.

Since, B lies between 1 and 2 and the unit length between 1 and 2 stands divided in 10 equal parts. Also, B lies 3 points ahead of 1. Therefore, B represents 1.3.

Since C and D lies between 2 and 3 and the unit length between 2 and 3 stands divided between 2 and 3 in 10 equal parts. Also C and D respectively lies 2 and 9 points ahead of 2.

∴ C represents 2.2 and D represents 2.9.

Question 10.

**(a)** The length of Ramesh’s notebook is 9 cm 5 mm. What will be its length in cm?
