Make such number lines for the decimal numbers : (a) 9.876 (b) 0.407. Class 7

Question 1.

Make such number lines for the decimal numbers : (a) 9.876 (b) 0.407. Class 7

Solution:

Do as directed.

Question 2.

In the number line shown below, what decimal numbers do the boxes labelled ‘a’, ‘b’, and ‘c’ denote? Class 7

The box with ‘b’ corresponds to the decimal number 7.5; are you able to see how? There are 5 units between 5 and 10, divided into 10 equal parts. Hence, every 2 divisions make a unit, and so every division is [latex]\frac {1}{2}[/latex] unit.

What numbers do ‘a’ and ‘c’ denote?

Solution:

a = 6 and c = 9.5

Question 3.

Using similar reasoning find out the decimal numbers in the boxes below. Class 7

Solution:

d = 8.01, e = 8.05

Solution:

f = 4.35, g = 4.5, h = 4.85

Question 4.

Which is larger: 6.456 or 6.465? Class 7

Solution:

6.465 is larger
