Answer 2

(a) 0, 10, 20, 30, 40, 50.

(b) 0, 8.1, 16.2, 24.3, 32.4, 40.5.

(c) 0, 2.2, 4.4, 6.6, 8.8, 11.

(d) 0, 3.33, 6.67, 10, 13.33, 16.67.

Explanation:

Part a.

From the given number line it is clear that

2 units = 20

So, length of 1 unit is

`(20)/(2)=10`

Therefore, the numbers on the number line are 0, 10, 20, 30, 40, 50.

Part b.

From the given number line it is clear that

4 units = 32.4

So, length of 1 unit is

`(32.4)/(4)=8.1`

Therefore, the numbers on the number line are 0, 8.1, 16.2, 24.3, 32.4, 40.5

.

Part c.

From the given number line it is clear that

4 units = 8.8

So, length of 1 unit is

`(8.8)/(4)=2.2`

Therefore, the numbers on the number line are 0, 2.2, 4.4, 6.6, 8.8, 11.

Part d.

From the given number line it is clear that

3 units = 10

So, length of 1 unit is

`(10)/(3)=3.33`

Therefore, the numbers on the number line are 0, 3.33, 6.67, 10, 13.33, 16.67.
