# Show the following numbers on the number line.

**(a)** 0.2

**(b)** 1.9

**(c)** 1.1

**(d)** 2.5

To do:

We have to represent the given numbers on the number line.

Solution:

(a) $0.2$ lies between the points 0 and 1 on the number line.

The space between 0 and 1 is divided into 10 equal parts.

This implies,

Each part is equal to $\frac{1}{10}=0.1$.

Therefore,

$0.2$ is the second point to the right of 0.

(b) $1.9$ lies between points 1 and 2 on the number line.

The space between 1 and 2 is divided into 10 equal parts.

This implies,

Each part is equal to $\frac{1}{10}=0.1$.

Therefore,

$1.9$ is the ninth point to the right of 1.

(c) $1.1$ lies between points 1 and 2 on the number line.

The space between 1 and 2 is divided into 10 equal parts.

This implies,

Each part is equal to $\frac{1}{10}=0.1$.

Therefore,

$1.1$ is the first point to the right of 1.

(d) $2.5$ lies between points 2 and 3 on the number line.

The space between 2 and 3 is divided into 10 equal parts.

This implies,

Each part is equal to $\frac{1}{10}=0.1$.

Therefore,

$2.5$ is the fifth point to the right of 2.
