Show the following numbers on the number line:

(a) 0.2

(b) 1.9

(c) 1.1

(d) 2.5

(a) 0.2

Here,

We can see that,

On a number line 0.2 lies between 0 and 1

In such a way that the space between 0 and 1 is divided into 10 equal parts.

Hence,

We can obseve that each part will be equal to one-tenth.

Now,

0.2 is the second point between 0 and 1.

(b) 1.9

Here,

We can see that,

On a number line 1.9 lie between 1 and 2

In such a way that the space between 1 and 2 is divided into 10 equal parts.

Hence,

We can obseve that each part will be equal to one-tenth.

Now,

1.9 is the ninth point between 1 and 2.

(c) 1.1

Here,

We can see that,

On a number line 1.1 lies between 1 and 2

In such a way that the space between 1 and 2 is divided into 10 equal parts.

Hence,

We can obseve that each part will be equal to one-tenth.

Now,

1.1 is the second point between 1 and 2.

(d) 2.5

Here,

We can see that,

On a number line 2.5 lies between 2 and 3

In such a way that the space between 2 and 3 is divided into 10 equal parts.

Hence,

We can obseve that each part will be equal to one-tenth.

Now,

2.5 is the second point between 2 and 3.
